      Description

      After the upgrade to 2.6.3, some of our test servers that were previously working started displaying badly broken CSS in IE8. This appears to be because of MDL-44936 - the CSS is now being chunked in the middle of a media rule.

      I am investigating and will provide a unit test & fix once I figure out what on earth it is. Unfortunately the problem does not happen on my personal dev server which is a bit annoying (presumably different modules on/off)...
