Musescore crashes upon copy-pasting tremolo across bar lines
1) Create a tremolo that alternates between two notes
2) Move the notes such that their duration causes the tremolo notes to cross a bar line
Expected behaviour: either Musescore obliges and allows the tremolo to be played, OR Musescore forbids the action and displays an error message (as is the case with trying to add tuplets between bar lines)
Actual behaviour: Musescore crashes.
