In Firefox, appearance:none on type=number still leaves the native stepper buttons in this rendering behavior, and the WebKit-only pseudo-element rule cannot target them.

+Reduced test: :target after replacing the targeted element
+
+
+
Fragment target replacement test

+

+  Load this file with #login. The initially targeted element is cloned,
+  a clone with the same ID is inserted at DOMContentLoaded, and
+  then the original is removed before final load processing. Chrome
+  retargets the remaining #login, so the green box stays visible.
+  Firefox leaves no element matching :target, so the box becomes hidden.
+

+Reduced test: auto-sized iframe flex item with aspect-ratio
+
+
Auto-sized replaced flex item

+

+  The gray flex container is 800×450 (16:9). The iframe has no width or
+  height attributes and only aspect-ratio: 16/9,
+  max-width: 100%, and max-height: 100%.
+

+

+  Chrome expands the iframe to the largest 16:9 size allowed by the container.
+  Firefox instead keeps the iframe's default 300px intrinsic width, producing
+  a 300×168.75 box in the center.

+Reduced test: narrow number input with appearance none
+
+
+
Narrow number inputs with appearance: none

+

+  Expected: the six one-digit controls have no native spin arrows and each digit is visible.
+  Chrome renders them this way. Firefox instead paints up/down number steppers in the
+  25px-wide controls, making them resemble drop-downs and consuming the digit area.
+  The reduced padding keeps the digits visible in Chrome while preserving the failing width.
+

+
+

+  
+  
+  
+  
+  
+  
+

+
+

+  Comparison:
+  
+  
+  
+

+
none, textfield, and default, respectively.

There is no differing OTP response, DOM structure, feature-detection branch, or user-agent-specific markup involved. The site's 25px fixed width and horizontal padding amplify the Gecko behavior: the retained spinner occupies the content box, makes each field look like a compact drop-down, and covers the entered digit. The reduced test proves the trigger without site scripts: the same `type=number`, narrow width, and `appearance:none` alone produce arrows in Firefox but not Chrome; Firefox's adjacent `appearance:textfield` control has no arrows, isolating the issue to Gecko's handling of the `none` appearance value for number controls.",

Computed styles on the first input were `width: 25px`, `padding: 4px 6px`, `box-sizing: border-box`, and `appearance: none`; both `appearance: none` and `appearance: textfield` feature tests returned supported. The live `style_v2.css` contains WebKit pseudo-element rules and Mozilla appearance declarations, while another loaded form-control rule also sets `appearance: none`; the resulting computed value on the failing element is `none`. The verified Puppeteer image probe counted 70 dark pixels in the top-interior arrow region.

There is no differing OTP response, DOM structure, feature-detection branch, or user-agent-specific markup involved. The site's 25px fixed width and horizontal padding amplify the Gecko behavior: the retained spinner occupies the content box, makes each field look like a compact drop-down, and covers the entered digit. The reduced test proves the trigger without site scripts: the same `type=number`, narrow width, and `appearance:none` alone produce arrows in Firefox but not Chrome; Firefox's adjacent `appearance:textfield` control has no arrows, isolating the issue to Gecko's handling of the `none` appearance value for number controls.",

OTP creation itself succeeded, with the success text present and three observed `/applySubmit` POSTs returning HTTP 200. Computed styles on the first input were `width: 25px`, `padding: 4px 6px`, `box-sizing: border-box`, and `appearance: none`; both `appearance: none` and `appearance: textfield` feature tests returned supported. The live `style_v2.css` contains WebKit pseudo-element rules and Mozilla appearance declarations, while another loaded form-control rule also sets `appearance: none`; the resulting computed value on the failing element is `none`. The verified Puppeteer image probe counted 70 dark pixels in the top-interior arrow region. In the reduced case, Firefox painted steppers for `appearance: none`, did not paint them for `appearance: textfield`, and painted them for the default `auto` number input. Site console errors such as missing jQuery/null elements were unrelated because the OTP UI and network operation completed.",

Each control had the same 25px by 36px geometry, padding, and computed `appearance: none`, but Chrome did not paint native spin buttons. The verified Puppeteer image probe counted 0 dark pixels in the arrow region. On the reduced test case, Chrome likewise suppressed the steppers for `appearance: none`, while its default number input retained normal number-control behavior. Console output contained an unrelated accessibility-script 404 and null `classList` exception; neither prevented OTP creation or correlated with the rendering difference.",

Firefox paints the native up/down stepper buttons inside those controls, whereas Chrome suppresses them. The reduced comparison further shows that Firefox removes its steppers with `appearance: textfield` but retains them with `appearance: none`; Chrome suppresses them with `appearance: none`. This direct paint difference consumes nearly all of the 25px control width only in Firefox and obscures entered digits.",

Opened the Abbott URL in Firefox DevTools, set a unique generated email using the native `HTMLInputElement.prototype.value` setter, dispatched an `input` event, clicked `Get OTP`, and waited until six `.otp-field-input` elements existed.\n4. In Firefox, probed the first OTP element with `evaluate_script`: it was ``, measured 25px by 36px with `padding: 4px 6px`, and had computed `appearance: none`; the form contained the successful-OTP message.\n5. In Firefox, inspected network requests and confirmed the relevant `POST https://www.jobs.abbott/applySubmit` requests returned HTTP 200; inspected console messages and found unrelated site-script exceptions but no error blocking OTP construction.\n6. Fetched the live stylesheet `https://cdn-prod-static.phenompeople.com/CareerConnectResources/ABLAUS/css/apply/style_v2.css` from the page and inspected its OTP rules, including the 25px width, WebKit spin-button suppression selectors, and Mozilla appearance declarations; also identified the loaded form-control CSS that contributes `appearance: none`, matching the failing element's computed value.\n7.

Firefox's fragment target remains associated with the removed original node (and is then cleared/stale), and it does not resolve the surviving replacement element with the same id during the remainder of initial loading. Chrome performs a later/final fragment resolution and assigns :target to the replacement #login. Consequently Firefox's final connected modal never matches :target and stays visibility:hidden/opacity:0. This is not caused by missing content, failed core resources, ETP, the Vue compilation warning, or user-agent sniffing; it is a Firefox-versus-Chrome difference in fragment target retargeting across DOM replacement during initial load.",

Its computed style was display:block, visibility:hidden, opacity:0, matching the site's base .modal styling rather than .modal:target, so the popup remained hidden. Vue 2.5.17 was present. Core document, CSS, Vue, and other site resources returned 200; the only observed failed resource was the unrelated https://rsms.me/inter/inter-ui.css (404). The Vue template compilation warning and a site ReferenceError were not causal because equivalent site-side errors also occurred in Chrome. Assigning location.hash to another fragment and then back to \"login\" after Vue had settled caused the surviving div#login to match :target and become visible, showing that the modal DOM and CSS work once Firefox performs a fresh fragment resolution.",

Its computed style was display:block, visibility:visible, opacity:1, so the Member Login modal displayed. The verified reproduction trace showed the same Vue 2.5.17 replacement sequence and shared Vue warning as Firefox, while core resources loaded successfully. In the reduced test, after the original #login was replaced during DOMContentLoaded, Chrome resolved the remaining replacement as :target and kept it visible.",

The observable divergence is fragment-target state: Firefox has no :target and applies .modal's hidden styles; Chrome assigns :target to the replacement #login and applies .modal:target's visible styles.

+// Reproduction: www.centuryasia.com.tw "Member Login" pop-up fails to load in Firefox.
+//
+// Root cause captured by this script:
+//   The login modal (#login.modal) is shown purely via the CSS :target rule
+//       .modal          { visibility: hidden; opacity: 0; }
+//       .modal:target   { visibility: visible; opacity: 1; }
+//   The page is loaded with the URL fragment "#login", but the #login element is
+//   rendered by Vue AFTER the initial navigation. Chrome re-resolves the fragment
+//   target when the matching element is later inserted, so #login matches :target
+//   and the modal is visible. Firefox resolves the fragment target only at
+//   navigation time (when #login did not yet exist), so :target never matches the
+//   late-inserted element and the modal stays visibility:hidden / opacity:0.
+//
+// Observable divergence asserted below:

+webcompat 2052489 - auto-width replaced element (iframe) with aspect-ratio in a flex container
+
+
+
+
Auto-width replaced element with aspect-ratio in a flex container

+

+  Each stage below is a 400×260 flex box (align-items:center; justify-content:center),
+  mirroring drmeth.com's flex flex-1 items-center justify-center wrapper.
+  The blue element inside has aspect-ratio:16/9; max-width:100%; max-height:100%
+  and no width/height set anywhere — exactly like the game's
+  <iframe class="aspect-video max-h-full max-w-full">.
+

+
Expected / Chrome: the block-level replaced element (iframe) STRETCHES to fill the
+   container's inline size (400px, then limited by 16/9 & the 260px max-height) → large box.

+   Firefox (bug): the iframe uses its DEFAULT intrinsic replaced width of 300px
+   (→ clamped by max-width:100% to 400px? no — it takes 300px intrinsic, height 168.75px),
+   collapsing to a small box. A non-replaced <div> with the same CSS fills
+   the width in BOTH browsers — the divergence is specific to auto-width REPLACED elements.

+
+

+  

+    

+      
+    

+    
A: <iframe> (replaced) — KEY CASE

+  

+
+  

+    

+      
div

+    

+    
B: <div> (non-replaced), same CSS

+  

+
+  

+    

+      no-src img (replaced)
+    

+    
C: <img> no src (replaced)

This is a browser divergence in fragment-target state/lifecycle, exposed by a fragile CSS-only modal design; it is not caused by resource loading, ETP, user-agent sniffing, or the common site console errors.",

The #login modal exists and CSS.supports('selector(:target)') is true, but document.querySelector(':target') is null and #login.matches(':target') is false while location.hash is #login. Its computed visibility is hidden and opacity is 0, exactly suppressing the modal. Firefox console contains the same Vue template warning and `ReferenceError: url is not defined` seen in Chrome; neither is Firefox-specific. Network shows the only notable failed stylesheet is rsms.me/inter/inter-ui.css (404), unrelated to .modal:target. Changing the hash to #other then #login after the DOM exists makes #login match :target and become visible with opacity 1.",

Chrome also logs the site's `ReferenceError: url is not defined`/Vue diagnostics and blocks rsms.me/inter/inter-ui.css (ORB), demonstrating those are not the cause.",

Read the verified Puppeteer script at `/tmp/autowebcompat-diagnosis-5v8c8c1m/2040305-gpt-5.6-terra.repro.mjs`, which navigates Firefox and Chrome to `https://www.centuryasia.com.tw/login.html?obj=l&obj1=i&ver=I+DfKKUJFcA=#login` and probes `#login`.\n2. Re-ran it with `NODE_PATH=/app/node/node_modules node /tmp/autowebcompat-diagnosis-5v8c8c1m/2040305-gpt-5.6-terra.repro.mjs`; Firefox reported hidden/opacity 0 with no target and Chrome reported visible/opacity 1 with target login.\n3.

In Firefox, set the fragment to `#other` and then `#login` after the page DOM was present; evaluated that #login then became :target and visible.\n5.

Because no definite width or height is supplied, Firefox\u2019s 300\u00d7168.75 result constrains the entire embedded game and breaks its non-responsive absolute-positioned UI. This is a CSS replaced-element/flex intrinsic-sizing interoperability dependency, not a network failure, JavaScript exception, unsupported aspect-ratio feature, ETP effect, or UA-sniffed code path.",

Computed iframe style was width: 300px, height: 168.75px, flex: 0 1 auto, aspect-ratio: 16 / 9, max-width/max-height: 100%; it has no width/height attributes. Its embedded #WRAPPER was only 294\u00d7152.1, which explains the overlapping fixed/absolute game UI. CSS.supports('aspect-ratio: 16 / 9') is true, so this is not absent feature support. Firefox console contained only \u201cInitializing auth app\u201d (no exception); its network inspection found no HTTP >=400 requests and game CSS/JS/font/images loaded successfully.",

The site/game document, CSS, scripts, fonts and images returned 200 (the game document redirected 301 then returned 200). Console warnings were StatCounter document.write and headless software-WebGL warnings, plus the auth log; none is a layout exception.",

Firefox retains the iframe\u2019s 300px intrinsic/default width and derives 168.75px height; Chrome instead derives width from the available max-height and uses nearly all available height (1251.55\u00d7703.98). The smaller Firefox iframe makes the game\u2019s fixed/absolute layout overlap.",
