Element moves around erratically when using mouse to adjust position of various elements (stems/augmentation dots etc.)

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

1. Create or open a new score with a dotted 1/4 note
2. Select just the augmentation dot, enter edit mode (F2), then use the mouse to drag it around
3. Expected: dot should follow mouse. Actual: dot moves around erratically.
4. Exit edit mode for the dot, then select just the stem of the note (release mouse afterwards)
5. Click and drag the mouse from somewhere in the middle of the stem (not where the drag handle is)
6. Expected: stem should lengthen/shorten based on mouse movements. Actual: stem lengthens/shortens erratically and uncontrollably

Also after such an operation, undo appears to undo not just the position/length adjustment but creating the note in the first place.
