Bug 100047 – Clear m_mediaSource reference when the MediaSource is closed

• Component: Media
• Status: RESOLVED FIXED

[Aaron Colwell]

The existing code in HTMLMediaElement holds the reference to m_mediaSource longer then it needs to. The object shouldn't be used again after it has transitioned to "closed" so I'm adding code to clear the reference when this transition happens.

Understood that it is not “visible to JavaScript”. What end user detectable effect does it have?

I don't believe it has an end user detectable effect. This change simply makes the object state more consistent so code can't access the object when it isn't supposed to.

resetting commit-queue? since the qt-wk2 failure doesn't appear to be related to my change.
