Draw with LUMINANCE_ALPHA texture produces wrong color

Project Member Reported by zmo@chromium.org, Jan 8 2018 
If we draw with a LUMINANCE_ALPHA texture with value (255, 255) in WebGL2 on Mac/Linux, we end up with (255, 255, 0, 255) instead of (255, 255, 255, 255).

On Windows or Linux with --use-gl=angle, we get the correct value of (255, 255, 255, 255).

It seems GPU command buffer handles this format incorrectly in ES3 contexts.

See https://github.com/KhronosGroup/WebGL/pull/2576 for a test case
