[tex4ht] Why tex4ht produces ", for \, instead of space in mathjax mode only?

I noticed something very strange. In my latex code I have \, in few
places, and these produce   ",  when compiled in Mathjax only instead
of a little extra white space as expected.

I am using \, in text mode, not in math mode.  Here is MWE



test \,

Compiled with

make4ht foo.tex "mathjax"


<!--l. 5--><p class="noindent" >test</p><!--l. 7--><p class="indent" >   test “,</p>

But when compiled with

make4ht foo.tex

Gives correct output, without the extra ", stuff

<!--l. 5--><p class="noindent" >test</p><!--l. 7--><p class="indent" >   test</p>

I can change \, with something else to get that little extra white space
I needed, but why does mathjax mode do this? Is this an issue with
mathjax itself or with tex4ht translation?

Here is the FULL HTML for the mathjax output if needed
