Your "logical display mode" would mean that e.g. Arabic and Hebrew
are written left-to-right, which would simply be unreadable. So that
would be my explanation for why such an editor doesn't exist.
It may be possible to find an editor that essentially does
"logical display" by simply using an editor that doesn't do
any bidi processing. But even editors that don't do any bidi
processing these days may end up with some kind of poor bidi
display, because of the way they use an underlying (OS or
window system) rendering engine.

For a somewhat different approach on how to edit bidi html
and xml, please have a look at
http://www.sw.it.aoyama.ac.jp/2005/pub/IUC28-bidi/ and
Comments and questions welcome.
