IE9, Firefox 5.0a2, Chrome 13 dev, and Opera 11.11 all say null.  I
agree that this is obnoxious.  I wound up writing a helper function
for my test suites that's basically function(node) { return
node.nodeType == Node.DOCUMENT_NODE ? node : node.ownerDocument }.
But it's not clear we can change it at this point.
