CSS issue: Topic header and post editor buttons getting off screen

I have updated Chrome to latest version (109.0.5414.117).

The same problems still occur on MetaBrainz since upgrade from 2.8.14 to 3.1.0.beta2 and server change but still not on try and not here on meta:

  • slight zoom in
  • dynamic header and footer buttons go off screen when scrolling

See top and bottom of the header and buttons that go off screen.

See at the end, I zoom out fully.
Then things are more fixed but it shows that it’s some out, as the header is not going all the way to the right border.

Maybe the problem is that the header is narrower than the page background?
