Details
(Whiteboard: [games])
Navigate to http://clb.demon.fi/dump/bugs/android_ff_attriblocation/lesson1.html with Firefox on an Android device.
Expected: A white triangle and a square renders. Works on desktop Firefox.
Result tested on a Nexus 4 Android device: a black screen is displayed.
I *think* Android fails when gl.bindAttribLocation(program, i, "attribName"); is called when the program does not contain attributes at all indices [0, i-1]. See the web console print as well, which shows the discrepancy: desktop binds properly to index 4, but Android still reports 0.
This is blocking from attempting some optimizations on emscripten fixed function GL pipeline emulation layer for mobile.

I can't access that URL anymore, but we should fix this if you're still seeing it. It's definitely a bug according to spec.

At some point in time, the domain name had to change due to reasons..
clb.demon.fi is now clb.confined.space, so the page is available at:
http://clb.confined.space/dump/bugs/android_ff_attriblocation/lesson1.html
I do not unfortunately have access to the Nexus 4 Android device anymore. Trying out on Huawei P10 Plus though, the issue does not reproduce, so maybe it has been fixed, or was Nexus 4 specific.
