Notes:

* The exception “MissingReferenceException: The object of type 'DockArea' has been destroyed but you are still trying to access it.“ may appear when trying to reproduce the issue but not in a way described previously. This exception does not appear when following the steps. Reproduction of this is included in the internal notes
