`max-world-size` in server.properties controls the maximum size of the world border.

However if you are running a server for the first time, or set it after the world border is already set, the world border will continue to be larger then the `max-world-size`.

I'm not sure if this is intended behavior, but it's certainly confusing behavior.

I would have expected it to either have some other effect then being the maximum world border size, or for the world border to be at maximum `max-world-size` on launch.
