Acid3 expects different traversal order from DOMIterator

I expect that we're adding a text nod or something.  We'll need to reduce:

    function () {
      // test 8: ignoring whitespace text nodes with node iterators
      var count = 0;
      var expect = function(node1, node2) {
        count += 1;
        assert(node1 == node2, "expectation " + count + " failed");
      };
      var allButWS = function (node) {
        if (node.nodeType == 3 && node.data.match(/^\s*$/))
          return false;
        return true;
      };
      var i = document.createNodeIterator(document.body, 0x01 | 0x04 | 0x08 | 0x10 | 0x20, allButWS, true);
      // now walk the document body and make sure everything is in the right place
      expect(i.nextNode(), document.body); // 1
      expect(i.nextNode(), document.getElementsByTagName('h1')[0]);
      expect(i.nextNode(), document.getElementsByTagName('h1')[0].firstChild);
      expect(i.nextNode(), document.getElementsByTagName('div')[0]);
      expect(i.nextNode(), document.getElementById('bucket1'));
      expect(i.nextNode(), document.getElementById('bucket2'));
      expect(i.nextNode(), document.getElementById('bucket3'));
      expect(i.nextNode(), document.getElementById('bucket4'));
      expect(i.nextNode(), document.getElementById('bucket5'));
      expect(i.nextNode(), document.getElementById('bucket6')); // 10
      expect(i.nextNode(), document.getElementById('result'));

      expect(i.nextNode(), document.getElementsByTagName('tbody')[0]);
      expect(i.nextNode(), document.getElementsByTagName('tr')[0]);
      expect(i.nextNode(), document.getElementsByTagName('td')[0]);
      expect(i.nextNode(), document.getElementsByTagName('td')[0].getElementsByTagName('p')[0]);
      expect(i.nextNode(), document.getElementById('instructions'));
      expect(i.nextNode(), document.getElementById('instructions').firstChild);
      expect(i.nextNode(), document.links[0]);
      expect(i.nextNode(), document.links[0].firstChild);
      expect(i.nextNode(), document.getElementById('instructions').lastChild);

      return 1;
    },

Mass moving XML DOM bugs to the "DOM" Component.
