This doesn't seem to happen for me. Instead I go soaring over it, and it rolls back down the hill. The lightest jump I can get; whether through keyboard or controller, results in this. On an especially good day, I'll also slide off the cliff. =[
I barely brush the button and this happens.
Perhaps I am jumping at the wrong time?
Edit: There we go! Jesus Christ that was a pain in the ass. I still don't know how I did it. But it's done.
