Bug: MS 3.1 Playback looping of Part Score ignored

I download the attached score from musescore.com and then using File > Parts created a separate "Part" score "Repique". Looping in the part score does not work properly. Try to loop a measure in the Repique part score while viewing it and the playback will ignore the selected part location and instead play the selection in the main score.

Feature request. To make going back and forth between associated scores easier, I recommend an option to sync the cursor of the scores so that selecting a measure in any of the part score updates the same location in the main score and visa vera.
