Observed an error locally when double-clicking on the modal backdrop to dismiss. Console log below:

The null object does not have a method 'dismiss'.

NoSuchMethodError: method not found: 'dismiss'
Receiver: null
Arguments: ["backdrop click"]

After a bit of digging, it appears that the change made on the ModalWindow to find the _top modal on the stack does not have a null check.

This can also be replicated in the example page.

I think a fix for this has been merged and the issue can be closed.
