Thrown items come from dead horse

There's the bug you already know about: when your horse dies in water, you appear to be sitting in third person mode.

I discovered another problem: whenever you throw blocks after your horse drowns, the items come from where your horse died. And you cannot pick up drops, although I did pick up a few things when the horse drowned, I think because for item dropping/picking up purposes, minecraft thinks you're still on the dead horse.
