What is the expected behavior for nodes in iframes?  IOW, with this sort of
DOM:

<body>
  <iframe id="a">
    <iframe id="b">
      <div id="node">

what is the return value for:
b.contentDocument.contains(node);  // I'd expect true, the spec seems to say
true
a.contentDocument.contains(node);  // I'd expect false, the spec seems to
say true
document.contains(node); // I'd expect false, the spec seems to say true
