Multipolygon rendering incorrectly

[mfarmer-ara]

Dragging and dropping a geoJSON file with multipolygon does not render as expected. It does render correctly when draggint the file onto geojson.io

However, looking at older versions of cesium it does render it correctly. I checked 1.92 and 1.108 and it rendered correctly in those.

Correctly rendering on version 1.92 (and up through 1.108)

Odd rendering on latest version on Sandcastle

File:
MultiPolygonExample.json

Thanks for the report @mfarmer-ara! This appears to be fixed in #11577. I would expect that fix to go out with the next release.

@ggetz Fantastic, I'll check again with the next release.
