Ahh, yes; I haven't done anything special for {multicols}.
Thanks for discovering the problem, which isn't hard to fix;
see below.

Yes, it's not easy to debug LaTeX's internal code.

However I've devised a simple 1-line fix.
It works as follows.

\let\if@boxedmulticols=\iftrue

then you get the correct columns.
This is safe, since with LaTeX2HTML all environments that are
to be typeset as images are necessarily "inner",
hence need to be "boxed". Thus it doesn't matter that we set
\if@boxedmulticols  to have a constant value of  \iftrue ,
whether or not the {multicols} package has actually been loaded.

The best place to insert code to generate this line
is within the  latex2html script, with the code block for
sub make_latex , where other such hacks at LaTeX internals are made:

"\\let\\real\@dbflt=\\\@dbflt \\let\\end\@dblfloat=\\end\@float\n" .
"\\let\\\@largefloatcheck=\\relax\n" .
"\\let\\if\@boxedmulticols=\\iftrue\n" .
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ insert this line
"\\def\\\@dbflt{\\let\\\@savefreelist\\\@freelist\\real\@dbflt}\n" .

Be careful with the escaped characters and double quotes;
that is:   \\ s, the \@  and the \n and '.' .

Hope this helps.
