Undo deletion of grace notes does not restore their beam properties

[Riley-Sullivan]

Issue type

Engraving bug (incorrect score rendering)

Bug description

When there are multiple beamed grace notes attached to a single note, there are cases where deleting one of them and then undoing the operation does not restore the beam properties to exactly how they were before deletion, and in fact leads to some very incorrect/impossible notation, especially with more complex combinations of grace notes of different durations. Also, an exported PDF will have the faulty layout. Not until you close and reopen the score do the grace note beams join correctly.

Steps to reproduce

See the attached screen recording for steps.
