Start playing a YouTube video and note that a SleepDisabler is created. Then close the browser tab. Notice that the destructor never runs: the SleepDisabler has somehow been leaked. This might be a media bug, or it might be a higher-level bug if some other code is leaking the entire media player (hopefully not?). I'm not sure what is happening. 1772995 1 pnormand 2021-06-28 01:52:48 -0700 I can't reproduce this after fixing bug 219353. 1773053 2 mcatanzaro 2021-06-28 07:11:46 -0700 I can no longer reproduce this, so I'll close this. But see also bug #219354. 1773110 3 mcatanzaro 2021-06-28 10:16:36 -0700 After more testing, I'm fairly confident this is reliably fixed.
