Subj : Getting an XmlObject from E4X changes top level element to xml-fragment

I'm calling an E4X script function from Java with Rhino and trying to
get an XmlObject from the function response, but the XmlObject I get
is an xml-fragment. The below code demonstrates the problem, the first
two printlns show:

   <s:Envelope xmlns:s="http://foo">
     <s:Body/>
   </s:Envelope>

but the final println of the XmlObject shows:

   <xml-fragment xmlns:s="http://foo">
     <s:Body/>
   </xml-fragment>

Am I doing this wrong is this a bug?

Thanks again,

public class Test2 {

  public static void main(String[] args) {
    Context cx = Context.enter();
    try {

       Scriptable scope = cx.initStandardObjects(null, true);

       StringBuffer sb = new StringBuffer();
       sb.append("function foo() {\n");

       sb.append("var s = new Namespace(\"http://foo\");");
       sb.append("var envelope = <s:Envelope xmlns:s={s} />;");
       sb.append("envelope.s::Body=\"\";");

       sb.append("java.lang.System.out.println(envelope);");
       sb.append("return envelope;\n");
       sb.append("}\n");
       String script = sb.toString();

       Script compiledScript = cx.compileString(script,"bla",1,null);
       compiledScript.exec(cx, scope);
       Function foo = (Function) scope.get("foo", scope);

       Scriptable jsResult = (Scriptable) foo.call(cx, scope, scope,
           new Object[] {});
       System.out.println("jsResult:\n" + jsResult);

       Wrapper wrap = (Wrapper) ScriptableObject.callMethod(jsResult,
           "getXmlObject", new Object[0]);
       XmlObject result = (XmlObject) wrap.unwrap();
       System.out.println("result:\n" + result);

    } finally {
       Context.exit();
    }
  }
}
