Looks like the test wants to create an event in an old way, yet it 
tests the typeof window.StorageEvent.

I'd really prefer to get the spec changed to not require this behavior. .createEvent is a very silly API.

r=me if you really prefer to do this though.

If this is bad for the web at large, maybe is worth trying to contact the creators of the test to fix it.

No many contact details at http://rng.io/about/ though...

I think we should land the patch, and if spec changes, remove support
for createEvent.
also, we should land this to Aurora too. I don't want to break pages too often.

Would you mind addressing the risk for this nomination?

Very low risk. We just enable creating storage events using document.createEvent()

Given the low risk evaluation, approved for Aurora 12.

Verified on Firefox 13 beta 3 that the test from: http://rng.io/ passes and that no error like the one from the Description is thrown.
