Opera has problems with uploading attachments on T-Online.de's webmail, it
boils down to an issue that might have some relevance for HTML5's definition of
the readyState property / document readiness calculation ( 
http://www.whatwg.org/specs/web-apps/current-work/multipage/dom.html#current-document-readiness
). 

What happens in IE is that when a window is being navigated away from the
current document, that document's readyState changes from 'complete' to
'loading'. (It would have made more sense in this case to have 'readyState' as
a property on the window, but that's a sin of designers past..).

HTML5 has not noticed this, it seems (or chosen to ignore it?), so the spec
as-written seems to asssume that readyState won't ever switch from complete
back to loading. The site sniffs for WebKit-based browsers and Firefox, because
they don't emulate IE on this point.

Now that we've realised IE does some extra stuff and found an important site
depending on it. I think switching back to 'loading' when some load is pending
makes sense.
