instanceof Element returns false

gistfile1.txt

I had a problem with a site my widget was embedded on.

  var el = document.createElement("div");
  el instanceof Element;
  >>> false

wat...
every other site on the planet returned true.

It turns out the culprit was Mootools v1.11.

Here is an example:
  Mootools 1.11  (this breaks):
  http://jsfiddle.net/f36kT/6/

  Mootools 1.2.6 (this works):
  http://jsfiddle.net/f36kT/7/

In case those links do not work, Mootools overwrites the Element global object with its own variable. 
This is a shitty idea, but whatever.

It looks like something was very broken and they fixed it post-v1.11.

So the solution......
  UPDATE MOOTOOLS
