Reparenting an actor BP to EditorUtilityActor does not give access to editor utility nodes

Ran into this while answering a UDN. A user was expecting to find the blueprint functions available to Editor Utility Blueprints after reparenting their actor to EditorUtilityActor. I confirmed that creating a Editor Utility Blueprint is different from creating a regular Actor blueprint and then reparenting to EditorUtilityActor: the second one does not grant access to editor functions. See repro steps.

Repro:

• Create an actor blueprint
• Reparent the actor blueprint to EditorUtilityActor
• Observe that one does not have access to editor nodes like Get EditorUtilitySubsystem

Expected:

• The reparented actor blueprint has access to editor nodes

For reference:

• Create an Editor Utility Blueprint
  • Right click content browser
  • Select Editor > Editor Utility Blueprint
  • Choose Editor Utility Actor
• Observe that one does have access to editor nodes like Get EditorUtilitySubsystem
