MooTools - Bing Maps incompatibility

[GamerJosh]

I have an existing project that uses MooTools that I would like to add a Bing Map to. I've discovered, however, that MooTools breaks Bing Maps. Here is a jsfiddle that shows the problem. If you watch your console when you click the Run button, you'll see that Bing throws an exception:

Uncaught TypeError: n.open is not a function

If you then disable MooTools, and hit run again, you'll see the map appears in the results pane.
