Per feature post-processing does not work with Ellipsoid(Graphics)

I made an adjusted version of the Per-feature Post Processing Sandcastle example that works with an Ellipsoid instead of a Model. This breaks the per-feature part. Post processing continues to work.

That does look like it might be a bug. I opened a GitHub issue to ask for more clarification:

Thanks for bringing this up.
