In essence what you do is:
You pick up an object from the Object Repository to drag to another folder.
(like copy)
Then you press ESCAPE button because you have second thoughts.
Katalon crashes.(not responding anymore)
expectation: It should be able to handle this.
Also: I didn’t take too much notice where the Object came from. Now there is no way to undo this.
this should also be easily doable. undo last drag and drop action.
