TOG-61 #comment Autohide controls during ad playback #time 1h

When using video sibling tag then player is in pause state, so need to
also validate against isInSequence
Clear mouseMoveFlag when stepping out of player

Need to clear the flag, otherwise the timeout for checking if controls
need to be shown will be triggered with mouseMove set to true and
controls will be shown, even due we’re out of the player.
