Repeat Measure sign in one staff of multi-stave inst. causes repeated playback of all staves

If have multi-staff *instrument* (e.g. attached) and want to indicate that one particular staff has a repeated pattern, then a repeat measure sign (%) can be placed on that staff.

However, musescore playback (as well as any audio export) will repeat every note from all staves of the previous measure, and not playback notes belonging to other staffs from the measure with the %. Expected behavior is to repeat notes from only the staff with the %, while still playing notes from the other staffs that don't have the %.
