[NTG-context] XML/HTML output of Math
Hi all,
I used to compile a beamer file with LuaLaTeX to generate a PDF
for presentation then convert the beamer file to XHTML with LaTeXML
for Web page.
Recently I begin to use ConTeXt so I try to get a PDF for presentation
and also XML/HTML output from a single ConTeXt file.
I have a few questions about XML/HTML output of Math.
1. In case inline math mode with \displaystyle, we get wrong output
of "\int_a^b"; lower limit and upper limit are interchanged
and further "b" is a bit larger and an integral symbol is rather small.
(It looks "\displaystyle" is not effective, e.g see "\frac".)
In case display math mode, we get very weird output of "\int_a^b".
It is difficult to explain how weird it is but something like
an output of "b_{\int}^a". Please check an attatched sample.
We get the similar kind of weird output of "\sum_{n=0}^{\infty}".
Due to these, it is impossible to use XML/HTML output of ConTeXt
in real use.
2. \math{\Vmatrix{\vI, \vj, \vk; a_{1}, a_{2}, a_{3}; b_{1}, b_{2}, b_{3}}}
\vI, \vj, \vk are disappeared in xml/html output. What happend?
BTW, if we put "a" (or any alphabet?) in fron of \vI, then
we get every elements (but of course we get unnecessary "a" also).

[NTG-context] Bug in LMTX: Color is lost after linebreak
Dear devs,
there seems to be a bug in LMTX. In the MWE below, the letter right
after the linebreak is black instead of gray. I'm using the latest
beta.
