Detecting whether certain events fire on certain elements in certain
situations by checking whether those elements have corresponding event
handler attributes isn't a sound strategy anyway, especially considering
things like bubbling events, author-dispatched events, events being fired
in subtly different situations (e.g. "input" events on <input> get fired
in more cases now than they used to be), etc.
If there are specific events that need better feature-detection, we should
look at those on a case-by-case basis.
