The dictionary doesn’t specify that. Often it won’t make much difference (assuming our understanding of physics is pretty good), and other times it would be clear from the context (“the ancients would have regarded human flight as supernatural”).
The point is that “supernatural” has an established meaning that is supported well by the etymology of the word. I don’t see much of a case for attempting to redefine the term it to mean something relatively arcane which the etymology gives no indication of.
