Errors on Shadow DOM's new ^ and ^^ combinators

[emagnier]

Orignally filed by @ebidel on compass at: Compass/compass#1490 and then by @chriseppstein on sass at: sass/sass#1071.

Shadow DOM's next Cat (^^) and Hat (^) selectors throw compiler errors. With it, one can write rules that penetrate the shadow boundary:

x-tabs ^^ h2 {
  ...
}

x-tabs ^ x-panel ^ h2 {
   ...
}

fyi -- syntax might change (again): http://lists.w3.org/Archives/Public/www-style/2014Jan/0603.html

The new syntax is supported by Sass - see sass/sass#1071.

#452 appears to be a duplicate of this issue although this issue mentions the no longer supported syntax so I would recommend closing this issue in favour of #452.

Yeah, we agree with closing this issue in favour of #452 .
