This in particular has been reproducible on Arch Linux with Firefox 123 and
Plasma 6.0.1
STEPS TO REPRODUCE
1. Play a video in full screen (unknown if this applies to all videos or just
DRM)
2. After a few minutes, pause the video with spacebar
3. Unpause the video and screen will blank until you alt-tab/mash Esc to leave
the fullscreen. You can also Ctrl+Alt+F2/F7 to "refresh" the HDMI connection
OBSERVED RESULT
Monitor registers an HDMI disconnection, need to perform some witchcraft to
restore normal usage
EXPECTED RESULT
Video simply unpauses and starts playing
