Hello, I’m rendering CZML ellipsoids and found that when I use a partial ellipsoid, it only renders the surface shell of the ellipsoid and appears hollow:

Is it possible to fill out the ellipsoid, like the ellipsoid viewer entities? I tried playing around with the `fill` property to no avail. Example of what I’m looking for:

Found the fix. `innerradii` should be properly camelcased as `innerRadii`, and needs to have non-zero values: [Cesium Sandcastle](https://sandcastle.cesium.com/#c=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)
