--- Comment #4 from Roger Fong <roger_fong at apple.com> ---
After emailing the Khronos group I got the following response from Kenneth Russel:

I don't mean to discourage your work but this is no small task either
from a specification or implementation standpoint. It would be
necessary to spec out a WebGL 1 extension combining the semantics of
both the ANGLE_framebuffer_blit and ANGLE_framebuffer_multisample
extensions. Users' code also has to be modified to take advantage of
multisampled renderbuffers. I think the effort would be better spent
getting a WebGL 2 implementation ready, which will include this
functionality in the core API.

Indeed renderBufferStorageMultisample has not been specced out and there are no 1.0.x conformance tests testing it. 

TLDR: I don't think we should do this because it never made it into the WebGL spec in the first place.
