Hi guys, I could have a look if it is not taken already.
we don't have an implementation yet. But it should be fairly straight forward. Webkit has implemented it and they had a couple of crashes around the lifecyle of the RegisteredEventListener that you'd need to watch out for.
Thanks, will start working on it.
Hi guys,

I've done the first version of the patch, was delayed by my holidays.
