This will likely be true for initial MSE implementations, but as time goes on
it is likely that more SourceBuffers will be supported as these implementations
mature. I think this is a quality of implementation issue.

Just disable/unselect the tracks that are provided by that SourceBuffer. That
should cause the SourceBuffer to be removed from activeSourceBuffers which in
turn should prevent it from causing playback to stall.
