[5.4] DRAFT Remove image fallback in HTMLHelper.php

[chinmayi-sudo]

Summary of Changes

This PR removes the unused image fallback from "HTMLHelper.php".

Previously, when "$text" was empty, an image fallback ("tooltip.png") was generated using "static::image()". This fallback is no longer required as the image is deprecated and not used in the current codebase.

Testing Instructions

1. Open a Joomla page where tooltips are used
2. Trigger a tooltip without text
3. Check:
   • No broken image is displayed
   • Tooltip still works correctly
   • No UI issues appear

Expected result

• No fallback image should appear
• UI should remain unaffected

Actual result

• Fallback image logic removed successfully

Documentation Changes Required

No

What if someone use own image?
This PR breaks such possibility.

Thank you for the feedback. I have updated the PR description as per the template.

As this code is not used in the core of joomla the test instructions are not complete

[brianteeman]

the code is obviously wrong

[chinmayi-sudo]

@brianteeman Thank you for the feedback. I understand that the change may not be correct and the testing instructions are insufficient. I will review the issue again and update the PR accordingly.

[brianteeman]

It is expected that at a very minimum BEFORE you start that you can replicate the problem. Until you can do that then you are not able to verify that your proposed code will fix something.
