Yes, it does a round trip. Such is life.

That may be due to me using some non-standard (Netscape-specific)
HTML. Eg 'absmiddle' as in
$q -> img({src => $image, align => 'absmiddle', width => 17, height
=> 17})
And when Mozilla has stabilized, in a year or so, I'll consider
installing it. Reports of its stability today are not going to sway
me :-). Such, too, is life.
