Concretely: OLD: Unless and until a new set of constraints is provided, the user agent MAY change its choice of track at any point, provided that 1) the new choice does not violate given user permissions, and 2) it notifies the application code by raising an event. It may wish to do this, for example, if the user interface or network congestion changes. Note that no such change will have an effect on the presence or absence of each type of track, merely the contents. NEW: Once selected, the source for a MediaStreamTrack MUST NOT change.
