() is the parent class is adding something in the Designer >> Hierachy tab (outliner)

  1. create BaseWidget (UserWidget) [add NamedSlot named “N0”]
  2. create Child1 (BaseWidget) [add NamedSlot to N0 named “N1”]
  3. create Child2 (Child1) [add an Overlay to N1]
  4. [add a Button to the Overlay]
  5. Try duplicating the Button by pressing Ctrl + D

results
The editor crashes

expected
The Button gets duplicated

Comments
