Groom bound to GeometryCache is unstable

This issue seems to occur only in 4.27 with DX12. Did not repro in 4.27 with -dx11, nor in UE5 DX11/DX12.

1. Open the project included in NewGroomTestUDN.zip
2. Play in Editor or Simulate.
3. Observe that the groom bound to the pig head sometimes explodes or flickers.
