Development Programming & Scripting UI

First of all Im aware its a poor Design choice to nest Named Slots and I encuntered the Bug/Crash only by curiosity.

To Reproduce:

  1. Create a Widget (lets call it ConfigTestWidget)
  2. Add 2 Named Slots and make one is nested bellow the other
  3. Create another Widget
  4. Add the ConfigTestWidget to the new Widget
  5. Add something to the Named Slot that is Higher in the Hierarchie (Note: at this point the Child Named Slot is technicly gone)
  6. Now Add something to the Child Named Slot

Picture

If the Parent Named Slot gets Content the Child Named Slot should disappear to Prevent adding to it.
