The pattern implementations use the class DeleteFeatureForPattern that extends DefaultDeleteFeature and therefore contain its own property doneChanges. Following the attribute chain delegate --> pattern --> wrappedDeleteFeature, there's a different instance of DefaultDeleteFeature that handles the actual object deletion and sets its own attribute doneChanges to true. The command stack performs a check to see whether any changes were made, and as far as I can see, it only checks the "outer" DeleteFeatureForPattern instance. The doneChanges attribute of this class is never set to true, so the entire undo stack is reverted. I'll attach a screenshot to illustrate the problem. 

Reproducible: Always
