Default values resetting for level instances of custom component pointers

When a code component contains a pointer to an actor, adding the component to a blueprint and setting the pointer to point to an instance of the same blueprint will cause the pointer to reset to "None" when the blueprint's defaults are changed/compiled.

This does not occur if the pointer is created as part of a class (code or blueprint) and then set to an instance of that class.

Regression:
No - behavior occurs in 4.13.2 as well

1. Open UE4 Editor (any project)
2. Add class based on SceneComponent (MySceneComponent)
3. Add the following to MySceneComponent.h

   UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = test)
   AActor* testActor;
   

4. Compile
5. Add blueprint based on Actor (MyActorBP)
6. Add My Scene component to blueprint
7. Add instance of MyActorBP to the level
8. Select MyScene in details panel
9. Set Test Actor variable to MyActorBP
10. In MyActorBP blueprint editor, select self and change value of Replicates boolean
11. Compile MyActorBP

Result:
The value of TestActor in the My Scene component resets to None after compile

Expected:
TestActor holds reference to MyActorBP instance after compiling the MyActorBP blueprint

References of inherited component is cleared on blueprint update
