Right-click staff menu not accessible on single line staff in Musescore 3
The right-click staff option menu (e.g., staff and menu properties) is often not accessible by clicking directly on a single-line percussion staff because the selectable area is too small.
Tested on the latest build: OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 3.0.0, revision: 026f90b
To reproduce, load score and right-click a staff line, not a note or rest.
