Dungeon 6: hero can be stuck when falling into a hole

But report from a youtube comment: https://www.youtube.com/watch?v=OgO53YtUns0

When you fall into the hole next to the switch at 16:14 there's a small glitch. You'll fall onto some stairs and you won't be able to move. I tried everything but Link was just stuck there.
