Placed instances do not update dynamic binding after hot reload

Adding a dynamic binding and preforming a hot reload sometimes causes the binding to not be registered by class/blueprint instances that already exist in the world. Instances need to be replaced from the Content Browser after the hot reload to register the updating binding.

Repro Rate:
4/10

Regression:
No - same behavior occurs with 4.16.3 (CL 3561208)

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

   UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = test)
   		class UBoxComponent* _box;
   
   	UFUNCTION(BlueprintCallable, Category = test)
   		void OnBoxOverlapBegin(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult);
   

4. Add the following to MyActor.cpp:
   • Add with other #include:

     #include "Runtime/Engine/Classes/Components/BoxComponent.h"
     #include "Engine.h"
     

   • Add to AMyActor::AMyActor():

     _box = CreateDefaultSubobject<UBoxComponent>(TEXT("MyBox"));
     	_box->OnComponentBeginOverlap.AddDynamic(this, &AMyActor::OnBoxOverlapBegin);
     

   • Add at the bottom of the .cpp file:

     void AMyActor::OnBoxOverlapBegin(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult)
     {
     	if (GEngine)
     	{
     		GEngine->AddOnScreenDebugMessage(-1, 4.f, FColor::MakeRandomColor(), TEXT("Enter"));
     	}
     }
     

5. Compile
6. Add instance of MyActor class to the viewport
7. Add the following to MyActor.h:

   UFUNCTION(BlueprintCallable, Category = test)
   		void OnBoxOverlapEnd(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex);
   

8. Add the following to MyActor.cpp
   • Add to AMyActor::AMyActor():

     _box->OnComponentEndOverlap.AddDynamic(this, &AMyActor::OnBoxOverlapEnd);
     

   • Add at the bottom of the .cpp file:

     void AMyActor::OnBoxOverlapEnd(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
     {
     	if (GEngine)
     	{
     		GEngine->AddOnScreenDebugMessage(-1, 4.f, FColor::MakeRandomColor(), TEXT("Exit"));
     	}
     }
     

9. Compile with the editor open
10. PIE

Result:
The instance placed in step 6 will have the BeginOverlap text (Enter) print but the EndOverlap text (Exit) does not print

Expected:
Placed instances update dynamic binding that is added/hot reloaded
