Details:

Hi all,

Today I updated my texlive 2020 installation and I compiled a LaTeX document
to HTML discovering that all subscripts and all supscripts in math where
broken, in the sense that were on the same line as the base.

My system is configured to store 1 backup version of texlive packages, so I
restore tex4ht to the version I had available:

tlmgr restore tex4ht 57127

I compiled the documents again and sub-/sup- script are working again.
I use the following command to compile

htlatex "sub-sup.tex" "mi" " -cunihtf" " -cvalidate" "-halt-on-error
-interaction=nonstopmode"

I am attaching the LaTeX example file and the configuration file.

With latest version:
<!--l. 39--><p class="noindent" ><!--l. 39--><math 
 xmlns="http://www.w3.org/1998/Math/MathML"  
display="inline" ><mi 
>a</mi><mi 
>b</mi></math>
</p>

With version 57127:
<!--l. 39--><p class="noindent" ><!--l. 39--><math 
 xmlns="http://www.w3.org/1998/Math/MathML"  
display="inline" ><msub><mrow 
><mi 
>a</mi></mrow><mrow 
><mi 
>b</mi></mrow></msub 
></math>
</p>
