[whatwg/fetch] Editorial: add note on event listeners & preflight (#578)

We already have this in the XHR spec, but I think it would be helpful to
readers to also have a note in the Fetch spec at point of use, because the
Fetch spec is what gets cited at StackOverflow and such as the source for
requirements on what causes a preflight. So omitting mention of this case from
the Fetch spec risks making people (continue to) forget this is among the
things that could be causing a preflight they’re running into but that they
don’t understand the reason for or how to prevent it.
