What effect does this have on local playback, e.g. if the user presses pause
while there is a real seek in progress? What happens when the real seek
completes and calls OnSeekComplete (or does something prevent it from doing so)?

Removed that line. Tried first to do that when switching to the remote player,
then removed it entirely to react on mediastatelistener, which come as response
to the seek request calls.
