For external resource links created with the <link> element, the URL is 
resolved when the resource is fetched, which can be delayed if the 
resource doesn't apply yet (e.g. because a media query doesn't yet match). 
This could lead to situations where different user agents had compliant 
behavior, unfortunately, but this is one case where I can't see how to 
avoid it without requiring suboptimal behavior.
