Describe the bug When an action with a shape modifies another shape, undo doesn't unselect this second shape which may result in unexpected behaviour afterwards

To Reproduce Steps to reproduce the behavior:

1. initial state
2. actor shape is dragged onto the arrow shape which causes the latter to split
3. press ^Z to undo

The result is that both shapes are selected and, if one tries to drag actor once more because one wasn't satisfied with the result, both shapes will be dragged.

Expected behavior No shapes should've been selected.
