Some settings on ellipsoids cause DeveloperError: All attribute lists must have the same number of attributes.

### What happened?

I found this error with an ellipsoid that stops the render of the viewer.

### Sandcastle example

I managed to reproduce it with different parameters on sandcastle [here](https://sandcastle.cesium.com/#c=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).

Start with the linked Sandcastle reproductions and trace the call stack through Geometry.computeNumberOfVertices, updateGeometryAfterSplit, and GeometryPipeline.splitLongitude. Confirm that the affected ellipsoid settings no longer trigger the attribute-count DeveloperError and that both examples render successfully.
