Public bug reported:

After a fresh start of firefox, screen saver is blocked properly when
playing video but after opening/un-suspending a few tabs with video,
inhibition stops working.

I was unable to come up with reproducible scenario but after a few hours
of browsing it usually stops working. Restarting firefox fixes the
problem.

The bug first appeared around August and affects both .deb and snap
packages.

Tested on Ubuntu-Mate 22.04.3, Xorg, both Pulseaudio and Pipewire (if that's 
relevant).
I don't see any relevant msgs in xsession-errors or system logs.
