Run the following example. <html> <head> <script> function test() { var SR = window.ShadowRoot || window.WebKitShadowRoot; var d = document; var ul = d.querySelector('ul.stories'); var s = new SR(ul); //make shadow subtree var div = d.createElement('div'); div.innerHTML = '<ul id="ip_wrapper"><content select=".shadow"></content></ul>'; s.appendChild(div); d.body.addEventListener('click', function (event) { alert('event.target.tagName=' + event.target.tagName); }, false); var event = d.createEvent('HTMLEvents'); event.initEvent ("click", true, false); d.querySelector('#li3').dispatchEvent(event); } </script> </head> <body onload="test()"> <ul class='stories'> <li id='li1'><a href='#1'>Link1</a></li> <li id='li2' title="li2"><a href='#2'>Link 2</a></li> <li id='li3' class='shadow'><a href='#3'>Link 3 Shadow</a></li> <li id='li4' class='shadow2'><a href='#4'>Link 4 Shadow 2</a></li> <li id='li5'><a href='#5'>Link 5</a></li> <li id='li6' class='shadow'><a href='#5'>Link 6 Shadow</a></li> </ul> </body> </html> This example shows tagName LI. But according http://www.w3.org/TR/shadow-dom/#event-retargeting (see steps 5 and 6 of event retargeting algorithm) UL (a shadow root) should be a relative target.

Let me take a look.

'LI' is correct in this case. That matches my intention and the implementation. Do you think the spec need to be fixed?

I believe spec needs to be fixed. I thought that parent calculation algorithm should be invoked in this case. It's not obvious for me that in this case it shouldn't be invoked.

Thank you for the reply. I think the it might be better to file a bug on the spec if the spec is unclear. So let me close this WebKit's bug. Please feel free to file a bug on the spec with a reference to this bug. (In reply to comment #3) > I believe spec needs to be fixed.
