[Andreas Farre [:farre]]

Hey Bevis, do you have an idea how that assert could trigger given this stack?

Comment 2

[Olli Pettay [:smaug][[e-mail]]]

This is an issue in HTMLTrackElement::LoadResource. It does stuff during stable state it shouldn't.

Look like the TabChild::ForcePaint fire the event.
Maybe we should modify HangMonitorChild::InterruptCallback()?

Comment 4

[Olli Pettay [:smaug][[e-mail]]]

Hmm, it is possible that we shouldn't interrupt when chrome JS is running. 
Perhaps mccr8 has some opinion here, or know who might have.

[Andrew McCreight [:mccr8]]

(In reply to Olli Pettay [:smaug] (please try to find other reviewers for non-web components patches) from comment #4)
> Hmm, it is possible that we shouldn't interrupt when chrome JS is running. 
> Perhaps mccr8 has some opinion here, or know who might have.

I'm not sure what this meta stable thing is. JS isn't supposed to be run during painting, but I guess this event dispatch thing doesn't run JS? Disabling tab switch painting while chrome is running would reduce its effectiveness, though we could in theory address problems there ourselves. Is this WebVTT code really never going to run from content?

I'm somewhat familiar with this mechanism (it was added in bug 1279086). mconley might be, too.
