Slightly cleaned up repro, since I wasn't sure if the DOM manipulation could be a culprit

This is working for me. What browser(s) are people seeing this on?

[Ocean-OS]

I'm currently on Chrome, on Android 15. I don't currently have access to a computer so I can't test it on other hardware.

I can't reproduce this in Firefox 139.0.4 on Windows 11 (27881.1000).

[Neptunium1129]

I'll check the unsupported Chrome versions later.
It works fine on the current version 137.0.7151.120 (Official Build) (64-bit).

this issue occurred in Chrome version 137.0.7151.122. The task closed.
