forEach does not work for HTML FrozenElementList

[larsbak]

document.queryAll('#status').forEach(void f(e) {});

yields an exception:
  Uncaught NoSuchMethodException - receiver: '[object NodeList]' function name: 'iterator' arguments: []]

The problem is that the itertor is not found in this special forEach wrapper.

FrozenElementList.prototype.forEach = function(f) {
  var $$list = this._ptr;
  for (var $$i = this._ptr.iterator$0(); $$i.hasNext$0(); ) {
    var element = $$i.next$0();
    f(LevelDom.wrapElement(element));
  }
}

If you know the Area- label, please set it and change status to Triaged.*
