Nested components do not appear in proper order in viewport instances

When an actor contains a nested component (components declared inside another component class), the hierarchy for the actor blueprint does not match the hierarchy of a placed instance of the actor

1. Open UE4 Editor
2. Create 3 classes (1 Actor - Charlie & 2 Scene Component - Alpha & Bravo)
3. Add the following to Alpha
   • .h

     UPROPERTY()
     UStaticMeshComponent* Fill;
     
     UPROPERTY()
     	UStaticMeshComponent* Stroke;
     

   • .cpp

     	Fill = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Fill"));
     	Fill->SetupAttachment(this);
     
     	Stroke = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Stroke"));
     	Stroke->SetupAttachment(this);
     

4. Add the following to Bravo
   • .h - #include "Alpha.h"

     UPROPERTY()
     UAlpha* AlphaA;
     
     UPROPERTY()
     UAlpha* AlphaB;
     

   • .cpp

     AlphaA = CreateDefaultSubobject<UAlpha>(TEXT("AlphaA"));
     AlphaA->SetupAttachment(this);
     
     AlphaB = CreateDefaultSubobject<UAlpha>(TEXT("AlphaB"));
     AlphaB->SetupAttachment(this);
     

5. Add the following to Charlie
   • .h - #include "Bravo.h"

     UPROPERTY()
     UBravo* Bravo;
     

   • .cpp

     Bravo = CreateDefaultSubobject<UBravo>(TEXT("Bravo"));
     Bravo->SetupAttachment(RootComponent);
     

6. Compile
7. Create a blueprint based on Charlie (CharlieBP)
8. Place instance of CharlieBP into the level

Result:
BP hierarchy lists Root->Bravo->AlphaA->Fill/Stroke->AlphaB->Fill/Stroke
Instance hierarchy lists Root->Bravo->AlphaA->Fill/Stroke->Fill/Stroke->AlphaB

Expected:
BP and Instance have matching component hierarchy
