When playing on MCPE with my brother, we keep fence gates open to keep water from flowing in certain areas while still allowing access. Every time the world is closed and reopened, the fence doors that were opened close. The reverse does NOT happen for closed fence gates, i.e. closed fence gates do not open.

What I expected to happen was the fence gates would be open.

What actually happened was the fence gates were closed.

Steps to Reproduce:
1. Place down a fence gate
2. Open the fence gate
3. Close the world
4. Reopen the world
