Hmm, I use firefox 68.0.1 of Ubuntu 19.04 and firefox 60.8.0
of Debian/unstable. I see the interchanging of limits with
both firefoxes. BTW, it seems Chromium doesn't support MathML.
If any Linux users could test the xhtml with firefox (or any browsers)
I believe it would help us much.

I'm not sure if I understand you correctly but I think MathJax
might be much better than MathML.

I see.

It helps me to some extent but with the original definition, we can
use \vI in both math mode (\math{\vI}) and text mode like "vector \vI".
So if ConTeXt could convert the nested mode switch correctly
it would be very nice.
Thanks for your info.

Re: [NTG-context] align figures verticaly centered in \startcombination mode

Dear all,
In the following example, “align=middle” works for horizontal center.
Is there any way to align two figures with different height in vertically

Thank you.

Each entry in the combination environment consists of the content and a
caption
but in your example you omitted the caption for each figures and as a
result the second
and figure graphics are taken as caption.
To get the expected output you can provide a empty argument for the caption
of each graphic or use a table to arrange the images.

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 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,
