Issue:
Nether portals can link to each other even though they should'nt.
A nether portal at x 1000 z 0 can sync to a portal in the nether at x 0 y 0.
This can't be intended because this allows players to travel thousands of blocks in no-time.
To reproduce:
Create a new world.
Go to x 0 z 0 in the overworld and create a portal.
Go through the portal then back.
Go and build a nether portal at x 1000 z 0
Go through it and see that its the same nether coords as the first portal created.

This is not world speficic. It can be reproduced in any world (at least so it seems). I've been able to reproduce this in several different worlds.
I also have this issue, please fix it soon because it's a real pain to travel so far in the overworld because my portal a few thousand blocks doesn't sync correctly :c
This is working as intended so far as I can tell.
A Nether portal in one dimension will link to a Nether portal in the other dimension within a distance of 128 blocks in x and z. This search occurs after adjusting coordinates. A Nether portal in the Overworld can be up to 1024 blocks away and it will still link (1024/8 = 128). Going from the Nether to the Overworld, the distance is 16 blocks (16*8 = 128).

Works as Intended, see MC-530
Is this phenomenon world-specific or can this be reproduced in the general case (brand new world)?
