<pre>Indeed, it seems it is not a Mesa's bug since in dev console in Firefox there
is next error:
*** Error compiling FRAGMENT_SHADER '[object WebGLShader]':ERROR: 0:6:
'gl_FragData' : cannot use both gl_FragData and gl_FragColor
ERROR: 0:10: 'gl_FragColor' : cannot use both gl_FragData and gl_FragColor
Which isn't a Mesa's error.
The WebGL test in question should have failed with current Mesa - see

title="NEW - "invariant" qualifier on outputs of GLSL ES fragment shader causes compilation error."
href="show_bug.cgi?id=107842">https://bugs.freedesktop.org/show_bug.cgi?id=107842</a>
However it passes on Chrome and it looks like Chrome completely ignores
invariant qualifiers...</pre>
