Nether portals built at different coordinates link to the same single portal in the Nether

Short description of the issue:

Hello, I have encountered a critical portal linking bug in Minecraft Bedrock Edition version 1.26.60.4 (non-beta). All Overworld portals map to one identical Nether portal coordinate instead of linking proportionally.

​Steps to reproduce the issue:

1. ​Build and light a Nether portal at Location A in the Overworld (e.g., coordinates X: 0, Z: 0) and enter it to generate a portal in the Nether.

2. ​Travel to a completely different location in the Overworld with different coordinates (Location B, e.g., X: 1000, Z: 1000).

3. ​Build and light a second Nether portal at Location B.

4. ​Enter the portal at Location B and check where it spawns/links in the Nether.

​Expected result:

Under normal game mechanics, portals built at different Overworld coordinates should map to their respective proportional coordinates in the Nether (X/8, Z/8).

​Actual result:

Regardless of where I build and light a Nether portal in the Overworld (at completely different coordinates), the portal in the Nether always spawns and links to the exact same single location.
