@import regexp error

This is the RegExp used when finding @import statements:

/\@import\s+(?:url([\'\"]?(._)[\'\"]?))\s_\;?/gim;

The problem is that the resulting url sometimes include "double quotes", so then the browser outputs a 404 error.

It works anyway, but the error is uggly.

You can change, for example, the "(._)" part for something like ([^\")]_

Thanks

Start by locating the @import regular expression described in the issue and inspect how its captured URL is passed to the browser. Adjust the quoted-URL matching so quotes are not included in the resulting URL, then verify that imported stylesheets no longer produce a 404 caused by double quotes.
