Keyboard navigation between staves broken on Multi-Bar rests

Issue type

Accessibility issue (e.g. for keyboard-only or screen reader users)

Description with steps to reproduce

If the user uses keyboard navigation to move on to a multi-bar rest they can then not use Alt + Up or Down arrows to move to other staves. This is especially confusing if the score begins with a multi-bar rest and the user then doesn't realise there is more than 1 staff present.

STEPS:

1. Open the attached score (or create one with at least 2 instruments and beginning with a multi-bar rest).
2. Press Right then left arrow to hear the multi-bar rest read.
3. Now Press Alt + Down arrow to attempt to move down onto the second staff (oboe on the attached score). The screen reader says "Down note in chord" and the user will assume there is only 1 staff.
