Ok, that matches my experience too -- that's why the spec says what it
says. :-) (The spec, when it is documenting IE features, is more about
documenting actual IE behaviour than about MSDN, which is notoriously
unreliable.)

Should that happen, we can revisit the issue... of course at that point IE
would be non-conforming, so maybe it would just be considered a bug. :-)

Well, it's not so much about our testing mechanisms so much as about what
Web authors have to deal with. If there's no way to ever see that it
starts in anything other than "loading", then for all intents and
purposes, it starts in "loading".

If you find any problems with doing this, please let me know, so we can
update the spec!
