107654 2013-01-23 03:08:20 -0800 Reference combinators do not match anything 2013-01-23 10:04:11 -0800 1 1 1 Unclassified WebKit DOM 528+ (Nightly build) Unspecified Unspecified RESOLVED DUPLICATE 82169 P2 Normal --- 63606 103230 0 a.semenov webkit-unassigned dglazkov oldest_to_newest 814055 0 a.semenov 2013-01-23 03:08:20 -0800 The Shadow DOM specification http://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html reads: "4.4 Matching Children, Distributed To Insertion Points Reference combinators match the children of a shadow host, distributed to the insertion points within a shadow tree. To match, all of these conditions must apply: * The combinator value must be select * The first compound selector of the combinator must match an insertion point * The second compound selector must match an element, distributed to this insertion point For example, .some-insertion-point /select/ div.special will match all div elements that have class attribute set to special and have been distributed to an insertion point that has a class attribute set to some-insertion-point." However the following sample code demonstrates that nothing is matched. <html> <head> <style> content /select/ a#link11 { display:none } </style> <script> function test(){ var host = document.querySelector('#links-wrapper'); var shadowRoot = host.webkitCreateShadowRoot(); var content = document.createElement('content'); content.setAttribute('select', 'a'); shadowRoot.appendChild(content); } </script> </head> <body onload='test()'> <div id="links-wrapper"> <a href='#10' id='link10'>Link10: Expected to be visible link</a><br> <a href='#11' id='link11'>Link11: Should not be visible</a> <p>the paragraph is not assigned to any insertion point</p> </div> </body> <html> Observed on Google Chrome version 26.0.1390.0 canary 814296 1 dglazkov 2013-01-23 10:04:11 -0800 Selector combinator has been banished in favor of "::distributed" pseudo-element function. Apologies, I haven't updated the spec yet. *** This bug has been marked as a duplicate of bug 82169 ***
