Creating MaterialInstanceDynamic for a moving/crumbled geometry collection component, the rendering position is reset to the initial location

Creating a MID makes the render state dirty and the engine will recreate a new scene proxy without the current attitude.
This results in rendering the object in incorrect location.

Here is a temporary work around : 

void UGeometryCollectionComponent::CreateRenderState_Concurrent(FRegisterComponentContext* Context)
{
    Super::CreateRenderState_Concurrent(Context);
//work around
    if (GetDynamicCollection())
    {
        TArray<FTransform> InitialTransform = GetDynamicCollection()->Transform.GetConstArray();
        SetRestState(MoveTemp(InitialTransform));
    }
//~work around
}
 

1. Open attached repro project [Link Removed]
2. Start PIE
3. Press 1 key to generate geometry collection
4. Press 2 key to Make MID on GCActor

Result

GC appears momentarily in initial position when falling/climbing.
When collapsed and stable, GC appears in initial position.
