Transposing a score with drums transposes the latter instrument

1. Open attached score
2. Select entire score for transposition
3. Change to C-Sharp Major.

Expected result: Only instruments with pitch are transposed.
Actual result: Drum notes change.

Should transposition exclude non-pitch percussion?

Already reported, but transposition doesn't work correctly either - transposition to C-major does nothing.

Using 0.9.6.3 and 10.4.11.
