Hi Tom,

thanks for the report. I thought I fixed fences not so long ago, when I removed most of instances of the deprecated <mfenced> element in the MathML configuration. <mo fence="true"> should be used instead. What I missed is that the whole expression must be in enclosed <mrow>, otherwise the fenced parentheses are not rendered correctly.

It should be fixed in the sources now.

Btw, it is best to use

make4ht math_text.tex "mathml,mathjax"

make4ht post-processes the generated HTML and fixes some issues especially in MathML. mathjax option will load MathJax, which fixes lot of rendering issues. For example it can display our wrong MathML code correctly even without the fix.

I used the command

mk4ht mzlatex math_test.tex "html,mathplayer"

I am using version 1.1

on the latex file attached and the results were nearly correct, but one issue is there are no braces/brakcets around the vectors/matrices - see the attached files (including source latex/ and compiled PDF)

So the bug is the lack of multiline braces/brackets
This may be similar to bug #340

screen shots / further details see question on stackexchange
