Repaint overlay scrollbar if resource is disposed.

Repaint overlay scrollbar if resource is disposed.

The previously painted resource can be disposed as the layer is
attached/detached from the LayerTreeHost. This isn't reflected by the
NeedsPaint status on the Blink-side Scrollbar so the scrollbar layer should
ignore the NeedsPaint status if it hasn't painted into its UIResource yet.
