This reverts commit 850e03d29f.
The previous commit solved this in a more general way. You can do:
[open-console]
profile-cond=p['user-data/mpv/console/open'] and p['current-tracks/video/albumart'] == false
profile-restore=copy
pause
Thankfully pause_on_open was just added and has not been in a release so
we can remove it.
