When changing the name of a named slot widget, it appear that any children contained in the the named slot (when the widget has been added to other widgets) will be cleared

Steps to Reproduce
  1. Open the editor
  2. Create a new widget blueprint
  3. Delete the canvas panel
  4. Add a named slot
  5. Name it "Something"
  6. Compile and save
  7. Create another widget blueprint
  8. Add the widget created above (with the named slot) to the newly create widget blueprint
  9. Add a text block to the "Something" named slot
  10. Compile and save
  11. Open the first widget
  12. Rename the named slot to "Somethingelse"
  13. Compile

Result: The Text block will be cleared/removed
Expected: The Named slot would be renamed and no children in any instances would be removed/cleared
