Bug of drawing polygon with holes by GeoJSON

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:

Could everyone help me, thanks a lot


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.
