Cannot adjust height of cross-bar beam under some circumstances

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

If a cross-bar beam is added between the first two bars of a system which is not the first system in the score, then the height of the beam cannot be edited. This occurs no matter whether the numerical beam height is edited in the 'Properties' tab, or the beam is dragged in the score.

To reproduce:

1. Create a new score with piano
2. Add two notes as seen in the screenshot below
3. Drag the beam up or down. The beam will move on the very first mouse-move event, and will then freeze. The amount of movement depends on how much the mouse is moved in this single event.

Workaround:
Type out the two measures with the cross-bar beam somewhere else on the score, adjust the beam height, and then Cut+Paste to the correct location.
