Get back default implementation of window.Map

Question

I'm writing Javascript code in a Salesforce.com Visualforce page. Unfortunately, Salesforce overrides window.Map with an incompatible map implementation. Is there some way to get back what used to be stored at window.Map?

This has already been answered in a generic context by @Raynos, but you can use an iFrame to recover the original Map:

var iframe = document.createElement('iframe')
document.body.appendChild(iframe)
var _window = iframe.contentWindow
VanillaMap = _window.Map
