I opened the xhtml with firefox and the only problem I see
is the ignored \displaystyle (which is why the integral looks small).
Inline looks fine otherwise, no interchanging of limits.
Well, as fine as it can be in firefox, which is pretty bad.

ConTeXt outputs b_a^\int in display mode; the order of the objects
inside the generated <msubsub> is wrong, which is clearly a bug.
And it seems to do this for all large operators.

I think this somehow triggered by the nested mode switch (\text{\math{}}) in the \vsym.
If I change that definition to the more simple:
\define[1]\vsym{{\textstyle\bi #1}}
it works ok. Whether that helps you ...
Best wishes,
