eqnarray does not work in mathjax mode.

I do not use eqnarray myself explicitly any more, but
this is from old latex files and noticed it does not work in mathjax:


%test for eqnarray in mathjax
%\usepackage{amsmath}%not needed for eqnarray


   \rightarrow\sum F&=& M x''   \\
   F \left( t \right)  + k R \theta + b R \theta' + H &=& M x''


Compiled with

make4ht foo.tex "htm,mathjax"

It looks like this


The question is, is eqnarray supposed to work in mathjax?
googling around I see examples where it works in mathjax on
the net.

Thank you,
