Sizing issues when using vertical frames and multi-measure rests

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

When resizing vertical frames for spacing staves, multi-measure rest widths on adjacent staves will lengthen uncontrollably, effecting the note spacing, bars per staff, and overall readability of the score. There is no method for manually resizing the width of multi-measure rests. This only happens in some parts/scores, not at all times.

STEP BY STEP

1. Open "Hot In Herre" (attached below)
2. Open "Alto Saxophone"
3. On a staff which has a multi-measure rest, add a vertical frame. (Palettes > Layout > Insert Vertical Frame)
4. Resize the vertical frame with the mouse our arrow keys, and observe the multi-measure rests on neighbouring staves widening.
