FTR, that was a regression in mutter in GNOME 41, now fixed upstream.

https://gitlab.gnome.org/GNOME/mutter/-/issues/2042

Fixed with

https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2124

Thank you for the detailed report and the reproducer, that was very
valuable to do the bisection in git and find the first commit which
introduced the regression!

Cheers
Olivier
