CSS doesn't update when attached with @import

Following the Brackets Smoke Tests here: https://github.com/adobe/brackets/wiki/Brackets-Smoke-Tests

CSS does not update when edited. Even worse the entire stylesheet seems to be lost! After edting this page to access desktop.css using a `<link>` instead of `@import` then it works (uh, partially -- see #22) I'm on the latest Firefox on Win7.
