For .md to .html conversion with MathML, \mathbf and \mathrm are translated into mi instead of mo ?

For .md to .html conversion with MathML, \mathbf and \mathrm are translated into mi instead of mo ?

The following minimum .md is used as an example
$A_1^2$ 

$\mathbf{A_1^2}$ 

$\mathrm{A_1^2}$ 


For .md to .pdf with LaTeX, the following command is used
pandoc ${mdname} --mathml --filter=pandoc-crossref --filter=pandoc-citeproc 
-s -o ${pdf_name} --pdf-engine=xelatex
. Note that the equations with \mathbf and \mathrm will be displayed as 
non-italic.

For .md to .html conversion with the --MathML option enabled, the following 
command is used
pandoc ${mdname} --mathml --filter=pandoc-crossref --filter=pandoc-citeproc 
-s -o ${html_name} -t html5
. Note that \mathbf and \mathrm are translated into mi tags instead of mo 
tags. As a result, the equation with \mathrm will be displaced italic, for 
example, when converted to .pdf through prince. Is this an unexpected bug ? 
If so, can it be corrected ?

Many thanks for your helpful efforts !

Re: For .md to .html conversion with MathML, \mathbf and \mathrm are translated into mi instead of mo ?

[John MacFarlane]

texmath translates \mathrm{x} internally into

EStyled TextNormal [EIdentifier "x"]

When rendering as MathML, texmath renders this as

  <mstyle mathvariant="normal">
    <mi>x</mi>
  </mstyle>

The "normal" variant is supposed to be non-italic
(since there's another variant "italic", but "roman"
isn't a defined variant, see
https://developer.mozilla.org/en-US/docs/Web/MathML/Element/mi.)

Sounds to me as if this may be a bug in prince?

(Btw, if you want A to be treated as an operator, which
is what mo means, try \mathop{A}_1^2.)
