103709 2012-11-29 21:54:03 -0800 [Shadow DOM]: reset-style-inheritance flag doesn't work for shadow insertion point 2012-12-10 20:51:07 -0800 1 1 1 Unclassified WebKit CSS 528+ (Nightly build) Unspecified Unspecified RESOLVED FIXED P2 Normal --- 103711 63606 103230 0 sgrekhov webkit-unassigned hayato oldest_to_newest 779807 0 sgrekhov 2012-11-29 21:54:03 -0800 According the Shadow DOM spec (https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html#styles) reset-style-inheritance flag should reset all inheritable CSS properties to their initial values at the upper boundary of the tree. This doesn't work in Chrome 23.0.1271.91 m. Example: <html> <head> <script type="text/javascript"> function test() { var SR = window.ShadowRoot || window.WebKitShadowRoot; var d = document; d.body.innerHTML = '<ul id="shHost">' + '<li id="li1" class="shadow">1</li>' + '<li id="li2" class="shadow2">2</li>' + '<li id="li3" class="shadow">3</li>' + '<li id="li4">4</li>' + '<li id="li5" class="shadow">5</li>' + '<li id="li6" class="shadow2">6</li>' + '</ul>'; var host = d.querySelector('#shHost'); d.body.setAttribute('style', 'color:red'); //Shadow root to play with var s = new SR(host); var div = d.createElement('div'); div.innerHTML ='<ul><content select=".shadow"></content></ul>'; s.appendChild(div); //Young tree var s2 = new SR(host); var div2 = d.createElement('div'); div2.innerHTML = '<shadow reset-style-inheritance=true></shadow>'; s2.appendChild(div2); } </script> </head> <body onload="test()"> </body> </html> Run the example above and observe the browser window. Red color style inherited from document body is not reset in spite of reset-style-inheritance=true attribute. If to modify example above to set resetStyleInheritance property this won't work anyway. In other words: var div2 = d.createElement('div'); div2.innerHTML = '<shadow id="shTree"></shadow>'; s2.appendChild(div2); s2.querySelector('#shTree').resetStyleInheritance = true; The modified script doesn't work anyway 779815 1 sgrekhov 2012-11-29 22:12:49 -0800 See also https://bugs.webkit.org/show_bug.cgi?id=103711 787991 2 hayato 2012-12-10 20:51:07 -0800 https://bugs.webkit.org/show_bug.cgi?id=103711 fixed this.
