That was my reaction too.  Per conversation with Mark, this ONLY happens when 
the file is served as "text/html".  Using XML or XHTML MIME types works fine in 

The reason CDATA sections in text/html cause issues is that the tag-soup parser 
doesn't really understand them, so the "<[CDATA[" part is passed to the CSS 
parser.  This last treats it as an error and skips forward, matching pairs of 
quotes, parentheses, and (most importantly) square brackets.  So the entire 
sheet is skipped.

Of course sending XHTML 1.1 markup (which these tests are) as text/html is an 
issue in itself...
