Comment on attachment 211044 [details] Proposed patch This seems weird. MediaStreamTrack is an ActiveDOMObject, but doesn't override any of ActiveDOMObject's methods besides ::stop(), and doesn't call setPendingActivity(). Why isn't MediaStream an ActiveDOMObject? After all, it has a m_stopped ivar too. If anything, MediaStreamSource is the active object, but MediaStreamTrack::stop() doesn't try to stop it's associated source. This seems highly weird, and I'm not entirely comfortable with it. But my problems with this method don't have much to do with this change specifically, so LGTM with reservations.
