Adding staff to instrument in score does not add staff to part; possibly crash involving undo / toggle mmrest
Ubuntu 14.04, GIT commit: 3c7a69d
See also #104431: Removing linked staff deletes part. I discovered both issues while attempting to answer a question on the forum (https://musescore.org/en/node/104406). I've lost track of what's expected and what is not. What I'm about to describe might be a feature for all I know, but I thought we weren't going to support this.
1) new score, treble clef template (or My First Score, I assume)
2) File / Parts
3) New All
5) Edit / Instruments
6) select staff, Add Linked Staff
Result: staff is added to score but not part. Like I said, this might be a feature, but FWIW, I think the user is more likely to want the linked staff in the part but not the score (which is what the OP in the forum thread I mentioend was asking about).
Again, as far as I can tell, everything actually *works* OK - no corruption or anything. I did see a crash, however, at some point after doing a series of undos etc (also adding a linked staff while viewing the part, which nonetheless adds it to the score) and then toggling mmrests off in the part. No luck reproducing that so far, though.
