Call-In-Editor functions in an EditorUtilityActor are not called in editor

In 5.1 through 5.3, Call-In-Editor functions within EditorUtilityActor Blueprints created via Create Advanced Assets/Editor Utilities/Editor Utility Blueprint are not callable in editor.

Prior to 5.3, creating the same asset as a Basic Asset/Blueprint Class and selecting EditorUtilityActor as the base class will allow the functions to be called in editor.

In 5.3, EditorUtilityActor's created as basic blueprint classes are recognised as an Editor Utility Blueprint and become uncallable.

1. Create a Blueprint via ContentBrowser/Advanced/Editor Utilities/Editor Utility Blueprint and select EditorUtilityActor as the type.
2. Create a function in this Blueprint. It will default to call-in-editor.
3. Place the Blueprint in a level
4. There should be no callable function on the placed actor
