"TypeError: node.getBoundingClientRect is not a function" on drop outside the document (FF 32)

[jledentu]

Hi !

In Firefox 32, I get an error :

TypeError: node.getBoundingClientRect is not a function

with the core-drag-drop demo , when I drop an "Hello World" element outside the DOM document, or outside the browser window.
I get a similar error in node-webkit 0.10.5 (chromium 35) :

TypeError: Cannot read property 'getBoundingClientRect' of null"

In the framed function, node seems to be null.

No problem in Chrome 38.
