Nether portals in overworld always link to the same portal in the Nether

It's the same issue reported for years that has yet to be fixed.

I make a portal anywhere in the overworld, and it links to the same nether portal in the Nether.

Making a new portal in the Nether will link to a portal in the overworld at the correct coordinates, but using any overworld portal takes me back to the original portal in the Nether.
