SUMMARY


STEPS TO REPRODUCE
1. Have "dim automatically" enabled (e.g. after 30s to see it quickly)
2. Start video playback (e.g. in Firefox)
3. Confirm in "Power and Battery" tray widget that sleep and screen locking are blocked due to FF "video-playing"
4. Wait period specified in 1.

OBSERVED RESULT
Screen dims after 30s

EXPECTED RESULT
Screen is not dimmed for as long as the video is playing.

SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.1
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1
Kernel Version: 6.9.6-200.fc40.x86_64 (64-bit)
Graphics Platform: Wayland

ADDITIONAL INFORMATION
I see no UX reason why screen should get dimmed whilst the video is playing. It just doesn't make any sense to reduce the experience, especially when watching full screen and not performing any mouse/keyboard actions.
