If an element has the name HTMLNames::inputTag, then it can't certainly be some other element, right? I agree that you can't assume that an element's name is HTMLNames::inputTag just because it's an instance of a HTMLInputElement but that's a separate issue.

Dangerous is probably the wrong word. Why would I ever want to call this method instead of just using toInputElement() though?
