insertAdjacentHTML should return a NodeList #63

I was referred here by annevk as WHATWG deals with insertAdjacentElement() spec, whilst w3c manages insertAdjacentHTML() spec - a bit confusing to a newcomer :)

At the moment of writing insertAdjacentElement() returns the resulting element, yet insertAdjacentHTML() doesn't have a return value. In my mind it should return a NodeList if successful. Has this been discussed in the past? Having a return (NodeList or otherwise) removes the need to do a querySelector/querySelectorAll/getElementByID after insertion - making it cleaner to use.

It makes more sense to me than the insertAdjacentElement() use case, where you already have a pre-existing reference to the attached element - however insertAdjacentHTML() starts from scratch, necessitating the lookup after insertion if you want to reference it later.
