UMG Widgets containing child widgets that have bound animations fail to save

Adding a child widget that contains a bound animation to a separate widget blueprint results in failure to save. Working in 4.22.3

Tested in: 4.22.3 CL#7053642, 4.24.1 CL#10757647, 4.25 CL#10889200

Notes: The "ChildWidget" is derived from the "TestWidget" C++ class and the "ParentWidget" is derived from UMG.UserWidget. The widget animation "TestAnim" is under protected in the TestWidget class.
