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

Thanks, Sergey. Will look into this.
