Creating TArray of components does not allow component elements to be edited in blueprints

When an array is used to declare actor components, the component elements that make up the array cannot be edited inside blueprints.

1. Open UE4 Editor (any project)
2. Add code to project based on Actor (MyActor)
3. In MyActor.h Add the following:

   	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
   		TArray<UBoxComponent*> Boxes;
   
   	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Test)
   		USceneComponent* MyScene;
   

4. In MyActor.cpp add the following:

   	MyScene = CreateDefaultSubobject<USceneComponent>(TEXT("MyScene"));
   	RootComponent = MyScene;
   
   	Boxes.SetNum(2);
   	Boxes[0] = CreateDefaultSubobject<UBoxComponent>(TEXT("NewBox1"));
   	Boxes[0]->AttachTo(RootComponent);
   
   	Boxes[1] = CreateDefaultSubobject<UBoxComponent>(TEXT("NewBox2"));
   	Boxes[1]->AttachTo(RootComponent);
   

5. Compile
6. Create blueprint based on MyActor (MyActorBP)
7. Open MyActorBP to the viewport tab
8. Select NewBox1 or NewBox2 in the component list

Result:
Transform widget is missing and Details panel is blank so the component cannot be edited through the blueprint

Expected:
BP components that are created as part of an array can be edited through blueprints.
