Bug#1118257: marked as done (libmutter-16-0: Caps lock behaviour is sometimes reversed and inconsistent after resume)

[Alessandro Astone]

I've recently looked into this for Ubuntu 24.04 LTS too.

https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4546 is not 
included in 48.6

In facts, it relies on some other API changes introducing 
clutter_keymap_get_modifier_state():

https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4395/diffs?commit_id=1940c6eba938a9413b93694573501153788d1f0f

These cannot be directly backported without breaking other consumers of 
libmutter, like gnome-kiosk.

The fix description doesn't really explain why the previous approach 
didn't work, so I also couldn't quite figure out how to fix it without 
relying on the new API.
