When in water on the positive x, y, and z axises, 16 blocks from the border you are unable to get out of the water.

Expected result:

You're able to get out of the water onto land on all parts of the world.

Actual result:

You bob up and down in the water just like you do when there is no land next to you.

How to reproduce:

1. Create an old style world with coordinates on.
2. Start going to the border in the positive x, y, or z coordinates.
3. Go into the water and try to get onto land

This effects people who make old style worlds and could also effect multiplayer and realms worlds if they use old style worlds.

A bug report was on the Nintendo Switch version in February of 2019 and was resolved ( I don't know if this was actually fixed)
