BeginPlay not called for Post-Process Anim Instance

Post-Process Anim Instances do not have BeginPlay called. The proposed fix is to add

if (PostProcessAnimInstance)
{
    PostProcessAnimInstance->NativeBeginPlay();
    PostProcessAnimInstance->BlueprintBeginPlay();
}

to USkeletalMeshComponent::BeginPlay

Open the third person template project. Delete the character from the level.

Within the third person ABP, on the BeginPlay event, print a string to screen.

Set the mannequin's post processing ABP to the third person ABP.

Place the mannequin in the level and play.

Notice: The ABP's BeginPlay is not called and no message is displayed.

Expected: The ABP's BeginPlay is called and a message is displayed.
