[Parity?] Overworld portals links to wrong Nether portals

The transport behavior of the portals in Minecraft Bedrock is weird and different from Java version.

Steps to reproduce:

1. Create a world with the seed in Minecraft Bedrock and Minecraft Java: 1582072495

2. Create a portal in -89 76 28 (HomePortalOverworldBedrock and HomePortalOverworldJava) in bot worlds and go in. Now in Minecraft Java you are in the coordinates -4 65 17 (HomePortalNetherJava) but in Minecraft Bedrock you are in -14 82 0 (HomePortalNetherBedrock). 

3. Exit the Nether

4. Go to 739 91 133 (RandomPortalOverworldBedrock and RandomPortalOverworldJava) in both Java and Bedrock worlds. In Bedrock you will find a destroyed portal, but in Java you will have to make one.

5. Enter those portals.

6. Now, in Minecraft Bedrock you will appear in -14 82 0 (HomePortalNetherBedrock), but in Java you will appear at 103 61 31 (a new portal, RandomPortalNetherJava)

Expected behavior:

Minecraft Bedrock should be behave as Minecraft Java. When I enter the RandomPortalOverworldBedrock portal, I should be appear in a new portal in the Nether instead in the HomePortalNetherBedrock portal, as occurs in Java. The distance between HomePortalOverworld and RandomPortalOverworld is more than 800 blocks, so I don't think that is the problem.

Actual behavior:

When I enter the RandomPortalOverworldBedrock portal I appear in HomePortalNetherBedrock
