BabylonJS Renders GLTF Incorrectly, Some Faces Are Wrong Way

I have some GLTF files which BabylonJS renders incorrectly; some faces are in wrong direction.

Cesium renders correctly, Three.js renders incorrectly as the same as BabylonJS.

GLTF files are converted from DAE with COLLADA2GLTF 2.1.2 for Win64. I have attached the zip containing .dae and .gltf.

I wonder if it's a bug of BabylonJS, or a bug of COLLADA2GLTF.
