It did in the past. I remember that effect from when we were
desperately trying to find a combination of text properties that would
work with both Emacs and XEmacs.

I just patched up preview-latex to place the invisible property on the
overlays it creates (obviously, not the desired default behavior).
Now this is using overlays, not text properties, but the results
should be pretty much the same.
And the results are that stuff is not found indeed when using isearch.
query-replace-regexp, however, still finds it. Non-interactive search
doesn't find it.
I also remember that in the Emacs-21.1 code base, placing the
"invisible" property on displayed stuff had the effect that scrolling
did no longer account for the amount of vertical space taken by the
image. However, with the current HEAD, this effect is not to be seen.
In case that you want to experiment with it, here is the patch I
used. Unfortunately, the main work is done in a macro, so you need
something like
(let ((load-path (cons "." load-path))) (load "preview.el"))
to let it take effect unless you recompile and reinstall
preview-latex.
