It's actually not entirely Gecko-specific.
Consider a display:none iframe. How should viewport-size-related media
queries be evaluated in such a thing? The specs don't define it, as far
as I can tell. In fact, the specs don't actually define anything useful
for the viewport of a framed document at all, as far as I can see. CSS
just assumes a viewport exists, and HTML doesn't define anything about
frames setting up a viewport for the document inside them...
But say they defined it. How would the viewport of a display:none
iframe be defined, exactly?
Last I checked, UAs just end up doing wildly different things in this
