What makes you think I don't?  I implemented this, after all.

I fail to get your point.

Anyway, it would seem like preview-latex behaves identical to Emacs
outlines and similar with regard to opening the target of search in
either incremental and non-incremental searches.

Indeed, if you use hide-leaves in a buffer, you'll find that exactly
the same behavior happens: C-s RET will open the overlay at the point
where the search ends, M-x search-forward RET won't.

So I think that the correct fix in the case of Emacs would be to let
search commands in general set `disable-point-adjustment'.

Though this does not seem to have an effect on outline-mode which
appears to work using isearch-invisible.  Sigh.

I still think that disable-point-adjustment seems appropriate for
search commands in general.
