I think we should really support breqn, I've tested it in the MathML
and image math modes and it failed with fatal error. So this is
something that we really should fix.

Yes, this isn't really nice. I posted Lua based solution to TeX.sx:

The Lua code can be easily modified to support more environments. In
other modes than MathJax, it will be probably more difficult, as it
seems that Breqn clashes heavilly with TeX4ht. I haven't looked at the
sources yet, so I don't know how serious it is.
