           Summary: [Shadow] parentTreeScope() of nested shadow DOM
                    subtree returns document().
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tasak at google.com

<body>
<div id="test">
</div>
<script>
    var div = document.getElementById("test");
    var shadow1 = new WebKitShadowRoot(div);
    shadow1.innerHTML = "<div id='E'></div>";

    var e = shadow1.getElementById("E");
    var shadow2 = new WebKitShadowRoot(e);
    shadow2.innerHTML = "<div id='F'></div>";

    var f = shadow2.getElementById("F");
    var shadow3 = new WebKitShadowRoot(f);
    shadow3.innerHTML = "<div id='G'></div>";
</script>
</body>

The shadow1, shadow2, and shadow3's parentTreeScope() are the same as document(). If creating the same DOM tree by using the following script, parentTreeScope() returns correct parent tree scope.

<script>
    var f = document.createElement("div");
    var shadow3 = new WebKitShadowRoot(f);
    shadow3.innerHTML = "<div id='G'></div>";

    var e = document.createElement("div");
    var shadow2 = new WebKitShadowRoot(e);
    shadow2.appendChild(f);

    var test = document.getElementById("test");
    var shadow1 = new WebKitShadowRoot(test);
    shadow1.appendChild(e);
</script>
