Description
In the code review / annotate UI, the horizontal scrollbar for a file's content sits at the very bottom of that file's scroll container. On any diff longer than ~100 lines, the scrollbar is pushed below the fold, so when a long line is clipped at the right edge there's no visible way to scroll horizontally from where you're reading.
The current workaround is painful: scroll all the way down to the bottom of the file, drag the horizontal scrollbar, then scroll back up to the line you were actually reviewing — and repeat if you need to pan again.
Steps to Reproduce
- Open the code review UI on a diff that is a few hundred lines long and contains lines wider than the viewport.
- Find a clipped long line somewhere in the middle of the file.
- Note there's no horizontal scrollbar in view — it only exists at the very bottom of the file's content.
Expected Behavior
Horizontal scrolling should be reachable from anywhere in the file. Two options:
- Sticky-bottom scrollbar: pin the horizontal scrollbar to the bottom of the browser viewport while the file's content is on screen (the pattern GitHub uses for wide diffs/tables), or
- Sticky-top scrollbar: render the horizontal scrollbar above the file content, stickied to that file's header, so it stays visible as you scroll through the diff.
Either works — the point is the scrollbar tracks the viewport, not the bottom of the document.
Actual Behavior
The scrollbar is anchored to the bottom of the file's full content height, so on long files it's off-screen during review. Reading a clipped line requires scrolling to the bottom, panning horizontally, and scrolling back up.
Environment
- macOS (Darwin 25.x)
- Plannotator via the Claude Code plugin
- Browser: Chrome
