Steps to reproduce:

In WebGL: enable a vertex attrib array other than 0 without binding a buffer.
The following code (see link) has a bug : i is never incremented.
https://dxr.mozilla.org/mozilla-central /rev/a461fe03fdb07218b7f50e92c59dde64b8f8a5b0/dom/canvas/WebGLProgram.cpp#485



Actual results:

Error message "Vertex attrib array 0 is enabled but has no buffer bound." regardless of the index of the actual enabled vertex attrib array.


Expected results:

Error message should be "Vertex attrib array N is enabled but has no buffer bound." where N is the actual enabled vertex attrib array.
