Indeed, the above @import rule is invalid per the CSS 2.1 core grammar, 
but I believe that the "User agents must close all open constructs at 
the end of the style sheet." part of §4.1 should apply.

Error handling is a big part of what we’re trying to specify with 
css3-syntax. The point is to make it interoperable.
