Edits done to a part are not reflected in playback

1) Open a score with parts.
2) Switch to a part.
3) Start playing a score, stop it.
4) Edit some notes (e.g. repitch a note, add or remove some notes, all while being in a part).
5) Play the score again.
Result: the previous version of a score gets actually played back.

This is a regression of 3.1 version.
Workaround is to switch a tab to another part/score and back again.
