There were a couple of problems here:
- The name of the event is different between platforms, logic to handle this has been added.
- The event object was not getting wrapped on Firefox.
- The wheel event parameters were different across all platforms.
The event name ('mouseWheel' vs 'DOMMouseScroll' vs 'wheel') has been fixed on ElementEvents, but not BodyElementEvents or DocumentElementEvents. I've opened bug #5414 to track fixing those up.
