2.0 -- changing a clef "breaks" the percussion stave.

If I change any of the clefs on the regular staves, (e.g., bass to bass 8vb), accidentals suddenly appear on the 5-line percussion stave where (of course) they don't belong, such as a sharp in front of a cymbal crash.

'Undoing' the clef change makes the drum stave accidentals go away. 'Re-doing' it brings them back.

I have not seen this behavior in 1.3.

Apologies if this bug was previously reported by someone else.
