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.

Yeah, we need to set up the proper object groupings in V8GCController.
