Restored the appearing behavior of media hosts

Previously the disappearbehavior of media
when transitioning between hosts got lost because
we've directly set the media into the end state (QS)
We're now instead avoid the media being put into the
overlay and put it therefore into the final position.
This also tunes the appear animation a bit to look
better since we also removed that part.

This largely reverts I9bcdb76b54c6303785a5783d84e876c162301b14
