The floating window doesn't update for me past the initial position. Windows 10 19045.5131. Chrome is up to date Version 131.0.6778.86 (Official Build) (64-bit)

That is quite strange Chrome behavior. Seems to only update it's background position when the window size changes. Looks like a Chrome bug to me! Probably some optimization effort that went wrong. I'm quite sure that it worked back in the days in Chrome.

This works as expected in Firefox.
