What I expected to happen was...:
The Boat should have been broken by me.

What actually happened was...:
I destroyed the Boat, died and when ijumped on the same position again the water was solid.

Steps to Reproduce:
1. Set up a pool of water andput a boat in it
2. Go to a height where you can die when jumping from it.
3.  Jump on the boat and just before you hit the boat left-click on it with a sword so that it gets destroyed. It takes a couple times but if you make it you should die and the boat should get destroyed.

4. Now jump again and youll die from hitting the water.
