[tex4ht] Is it possible to fix tex4ht links so so it ends at top of page?

[Nasser M. Abbasi]

I thought I should also make MWE.

The problem really happens when the set up is like this:

There is table of content. Each link in the TOC opens
a new separate web page because split is 2. (In this example).

So given a book with 2 chapters. There is one TOC on the
main page and two separate pages. One for each chapter.

If the chapter has too much text to fit on monitor screen,
you will see the shift. i.e. when clicking on the link in
the TOC, the new page will open shifted little lower, so the
navigation bars do not show. (one has to move the vertical
slider bar up to see them and remove the shift manually).

This MWE shows this problem. So the links that needs to be fixed
are really the ones generated when making the TOC.

Normal direct links generarted using href are no problem.

\Configure{tableofcontents*}{chapter}
\else
\setcounter{tocdepth}{0} %for toc
\tableofcontents
\fi
\tableofcontents	

\chapter{chapter 1}
\lipsum[2-4]

\lipsum[2-4]

\lipsum[2-4]
\chapter{chapter 2}
more important text
