Description Cameron McCormack (:heycam) 2022-09-27 14:47:41 PDT

In bug 243062, we added an optimisation to avoid the expensive computation of an updated MediaSessionInfo object when the previous state had no currentSrc URL and the current state doesn't either.  But this excludes media elements that have a srcObject, whose state we still want to reflect through media sessions.
