           Summary: elements
                    APPLET,FIELDSET,FRAME,IFRAME,IMG,INPUT,OBJECT,SELECT,T
                    EXTAREA are not able to host shadow tree
           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: a.semenov at unipro.ru

The specification http://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/shadow/index.html reads:
"The shadow DOM allows multiple DOM trees (in addition to the document tree) to be composed into one larger tree when rendered. The existence of multiple DOM trees is enabled by letting any element in the document tree to host one or more additional DOM trees."

However elements APPLET,FIELDSET,FRAME,IFRAME,IMG,INPUT,OBJECT,SELECT,TEXTAREA are not able to host shadow tree.

<script type="text/javascript">

function A_04_00_01_test(elementName) {
    var d = document;
    var SR = window.ShadowRoot || window.WebKitShadowRoot;

// create element
    var n = d.createElement(elementName);
    d.body.appendChild(n);
    try {
        var shadowTree1 =  new SR(n);
        d.write("<P>"+elementName+": OK");
    } catch(e) {
        d.write("<P>"+elementName+": " + e.name + e.message);
