Re: Exceptions in event listeners triggered by dispatchEvent().

I think it would be great if dispatchEvent dispatched the event at
end-of-microtask or some such. Mainly to avoid reentrancy issues for web
authors. And returned a Future<boolean> to indicate if default action
should be run.

But there is absolutely no way that that is compatible with existing
content.

Best we can do is to introduce a new dispatch function that works that way.
