In these files there is a logic that is supposed to apply only when the media element is playing a regular src URL (i.e., not when it's a MediaStream).

During the removal of MediaStreamRegistry a check that it was not a MediaStream URL was removed. This check was incomplete (and is now unnecessary since MediaStream URLs don't exist anymore).

However, a check that the element is not playing a MediaStream should be added.
