UX/Interaction bug (incorrect behaviour)

Bug description

Editing the noteheads in the edit of the drumset does not affect their final shape in the score.

Steps to reproduce

1. Create a glockenspiel staff (or any other instrument with a definite pitch).
2. Add a edit staff type anywhere by changing the instrument in parallel.
3. Open the edit drumdset, change the shape of the notehead to any other.
4. The shape of the notehead of the score will not change.

@zacjansheski FYI (Happy to discuss this one further btw).

I also noticed that a score with a custom group of noteheads cannot be uploaded to musescore.com . A few hours after uploading the score, page 404 "Page not found" appears.
@bkunda, should I publish this as a separate issue, or will my comment be enough to solve this together with the current issue?
