Re: [whatwg/dom] Improving ergonomics of events with Observable (#544)

Well, it's guaranteeing that promise reactions only run on an empty stack, which is a fairly important invariant that's ingrained into a lot of promise-using code. I personally don't think that introducing a new promise type whose timing is different from all others is a good idea; I think it increases the chances of unexpected behavior, instead of decreasing it.

If you really think `first()` is an attractive nuisance whose downsides outweigh its benefits, then perhaps we should just take that as implementer feedback and remove it, but I think it would be a shame, as I see lots of useful ways to use it which won't ever encounter this problem.
