Repeats no longer play in new or old .mscz files.

Since upgrading to Musescore Version 3.5.0.28537 Revision 43c5553, on latest macOS 10.15.6 (macmini).
On playback, repeats are ignored. This happens no matter if I click the "Play repeat" button or not. It also
happens with both old .mscz files, where playback used to play the repeat correctly, and newly created ones.
I've included a newly created file as an example.
