I see DisplaySVGGeometry::HitTest stalled waiting for D2DFactory::CreateStrokeStyle()
I expect it's waiting for access to D2D.

Not sure if this is a commen resource contention?
Moving to Core::WebPainting, I believe that's the right component.

The severity field is not set for this bug.

I'll move this to Graphics, since this is almost certainly D2D contention between the main thread, and the OMTP threads.

This should be fixed once WebRender is enabled.
