Boats Duplicate when placing in Survival

The reason this is in private is because this can potienally be used to grief a survival world or server.

This exploit allows unlimited boats just simply by placing them.

It's rather simplistic.

How to replicate

1. Open existing survival world or a create a new one world - No cheats, I did on Hard.

2. Create a boat.

3. Place boat

Expected: Boat leaves inventory after placed.

What actually happens: Boat stays in inventory, as though in Creative.

Affects all boats regardless of material.
