Re: [heycam/webidl] A non-optional dictionary argument makes sense at times. (#130)

It's very much a special case though and in case of `MutationObserver` I don't think requiring at least one member would even help that much since we'd still have to check it's one of the members that can be supplied standalone (e.g., only specifying `subtree`).

So given that I don't think there's enough to overturn this. You might want to point it out in a note though.
