Bug of drawing polygon with holes by GeoJSON

CesiumJS

Hello,
When I load a polygon from geojson, the rendered geometry looks a bit confusing.
The polygon has two holes, if I remove one of the holes, the result becomes correct.

The geojson file is here:

The screenshot of geometry is here:

Hello,

There is a known issue with our polygon triangulation that causes errors for polygons with holes. The issue is open here: https://github.com/AnalyticalGraphicsInc/cesium/issues/3044

Thanks for providing a sample GeoJSON file. I’ve attached it to the GitHub issue so we can look into it.

Best,

Hannah
