Note that (CSS-driven) XBL is probably the long term solution here.

At the moment the DOM doesn't support this kind of UA. There is only one
View -- the defaultView, which in Web Apps is defined as being the same as
the global window object -- and thus only one set of computed styles, and
thus only one set of stylesheets that apply.
Frankly I would consider such a UA to be non-compliant if it used the
same window object for both rendering modes.
