Hi Remy, and others.
Got some good news for you regarding this bug.

This is indeed a depth-precision issue. However, we were having issues with D16Unorm formats in other parts of ANGLE as well, mostly related to setting a depth bias. You can read more about that bug here. https://bugs.chromium.org/p/angleproject/issues/detail?id=6597

Regardless, the end result is that we've upped all depth buffers to 32 bit floating precision in more recent versions of the WebGL backend when using metal. This seems to have fixed your demo's issue.
