Bug: Unpausing all players simultaneously does not work after adjusting a singe player

[Toastie]

Steps to reproduce:

1. Open multiple players of a replay
2. Pause all together with shift + space
3. Unpause a single player with either space or the play/pause button
4. Pause this player again, all players should be paused now, the focus stays on the now again paused player
5. Unpause all players with shift + space again

Expected behaviour at this point:
All players start playing again.

Actual behaviour:
All players execpt the manually adjusted player start playing immediately and continue to do so.
The player that has been adjusted starts playing and after that immediately pauses again.

Known workarounds:
After step 4, exiting fullscreen on the adjusted player and entering again causes the expected behaviour to occur after step 5.

Known affected versions:
1.4.0. and 1.4.4.
