Description Tony Gentilcore 2011-11-11 10:13:08 PST 
Chromium fails the media/track/tracklist-is-reachable test which was introduced by r99984.

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=media%2Ftrack%2Ftracklist-is-reachable.html

Apparently V8 doesn't allow us to set expando properties on non-DOM objects that are also EventTargets. Eric Carlson informs me the JSC code for this is in JSTextTrackListOwner::isReachableFromOpaqueRoots

We probably need to do something similar.

My patch just sets expectations. Reopening to track the real fix.
Comment 4 Adam Barth 2011-11-13 23:01:35 PST 
Yeah, we need to set up the proper object groupings in V8GCController.
