Ellipse on ground has hole in it when camera is perfectly perpendicular to ground

Sandcastle. This flies to an entity by sampling the ground position there and flying to that lat/lon/height.

It produces a hole in the middle of this ellipse which goes away if the camera is tilted:

This appears to happen with polygons too. Instead of an inner circle it'll be a smaller polygon of the same shape.

I imagine this would happen with all GroundPrimitives

Once #9108 is merged it will be possible to work around this bug by setting viewer.scene.logarithmicDepthBuffer = false;

This seems to only happen in CesiumJS 1.71. Could not reproduce in 1.70 and 1.69.

git bisect points to c72dfbb from #8850. First guess is that some geometry is getting cut off by the near or far plane. CC @IanLilleyT
