Test case.

Rendering work fine with attribute 0 disabled and without OES_vertex_array_object extension enabled. But if the extension is enabled and a non-null VAO object with 0 attrib disabled is bound, nothing renders.

Test page: https://codepen.io/dmikis/full/VXrBBe. A picture expected, black canvas is rendered instead.
