After a fresh start of firefox, screen saver is blocked properly when playing video but after opening/activating(unsuspending) 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.
