Crash when a custom shortcut is used to open Staff/Part Properties and change instrument

Issue type

Crash or freeze

Description with steps to reproduce

This crash is likely to effect screen readers using keyboard instead of right click mainly, so is also an accessibility issue.

STEPS:

1. Go to Edit/Preferences Shortcut, search for properties and define a shortcut for Staff/Part Properties.
2. Move focus to any note of a score (may need to have two staves or more).
3. Press your assigned shortcut to open the Staff/Part Properties dialog box.
4. Tab down to Replace Instrument and press enter.
5. Select a new instrument and Tab to Ok and press enter.
6. MuseScore crashes and closes.
7. Expected Behaviour: Returns to Properties dialog box with new instrument added.

Is this related to having had focus on a single note rather than range selection when the dialog was launched?
