Untamed horses dont throw players off in water thats deeper than two blocks.
What I expected to happen:
The horse throws me into the water because the water is too deep.
What happened:
I stayed on the horse until it threw me off because it still needs to be tamed.
Steps to reproduce:
Spawn an untamed horse in a deep water pool, ride it. (The horse wont go underwater and throw you off, it will swim and throw you off once it throws you off from the taming mechanic)
Cannot reproduce in 16w42a.
