[tex4ht] is it possible to have complete support for breqn package in tex4ht?

I've tried an older test file you sent me, and all Breqn equations
were converted to images by default. What doesn't seem to work is the
long line-breaking feature, which is a bit problematic. TeX4ht sets
long line widths by default, so I thought that this may be the
problem, but even if I set these widths to a much smaller size, the
line breaking doesn't seem to work:

\Preamble{xhtml}
\makeatletter
\AddToHook{env/dmath/before}{% test that line width is really small:
\typeout{*************** linewidth: \the\linewidth, \the\eq at linewidth,
\the\displaywidth, \the\columnwidth}
}
\begin{document}
\textwidth=6em
\linewidth=\textwidth
\columnwidth=\textwidth
\eq at linewidth=\linewidth
\makeatother
\EndPreamble

I am not sure what is going on here, maybe Breqn uses also some other
dimensions or macros overridden by TeX4ht, so the line-breaking
doesn't work.

Best regards,
Michal
