Boats fall through terrain

Boats when placed on land will fall through the ground suffocating you and any passenger thats aboard.

Steps to reproduce:

Grab a Oak boat (May happen to others havent tested)
Place boat on dry land 
Right click to get in boat.
>Sink two blocks below.

 

Note: This bug also happens in water. If you place a boat in water it'll sink a block under the water once u enter the boat.
