Dragging a CesiumCartographicPolygonPrim in the Stage Window crashes app

[corybarr]

(Confirmed issue in both main and #626.)

To reproduce:

1. Open the attached .usda file.
2. Create a Scope
3. Drag one of the CesiumCartographicPolygonPrims into the Scope:

clippingTest.twoPolygonLayers.usda.zip

Here's a .usda with globe anchor schema changes needed for testing with #626

The stack trace doesn't seem to be in our code. I wonder if it has to do with Fabric and Basis Curves.

That's what I think. I think we should ship with this, then let NVIDIA know once they can reproduce it.

Also, there's no crash with the Fabric Scene Delegate disabled.

A regular BasisCurves doesn't crash when moved

Fixed in #648
