Sentry Crash Report:

Description James Eder 2025-05-20 00:59:18 UTC 
SUMMARY
KDE instantaneously suspends my computer the moment my YouTube video finishes playing.

STEPS TO REPRODUCE
1.   Set to suspend after 10 minutes of activity.
2.   Play a YouTube video that is longer than 10 minutes.
3.   Do not move mouse or use keyboard.

OBSERVED RESULT
System will suspend the instant that the video finishes rather than waiting 10 minutes. This is very annoying and disruptive.

EXPECTED RESULT
System suspends 10 minutes after activity stops and that playing a video is considered activity.  The countdown should start when the inhibiting lock is released.

Can confirm, the timing has to be quite close. 

I think we should just restart the timer when blocking the sleep is turned off.

PowerDevilAction: refresh action timers on inhibition changes

When inhibitions change, action timers should be restarted.
If they're not restarted, action timer may run to 0 right after
a video playback ends for example, running the action abruptly.
