Bouncing from a bed to the edge of an anvil does something weird.

In the survival world I was talking about previously in my other issue I had found, I bounced from my bed onto the anvil next to it accidentally and it still made the bouncing effect as on the bed. I did it several times and it only happens on the very edge of the anvil. Either the hit box of the bed is too high when on top of an anvil next to it or I don't know.
