Chunks in all dimensions have their biome replaced with an Ocean biome upon reloading in updated older worlds created prior to <1.17.40

In worlds created prior to 1.17.40 (as of my testing) and or updated to the Non-Preview (1.21.30 currently) changes parts of the Nether Biomes to an Overworld Biome (most likely Ocean) upon reloading for a second time wiping out the Nether Biome data in some chunks.

Steps to reproduce:

1. Import the provided test world into 1.21.40.23 Preview and load
2. Observe the Nether Biomes are expected
   
3. Enter the portal and come back or Exit the world and rejoin it
4. The Nether Biomes switched to an Overworld Biome and the fog is gone
   

The Overworld and End dimensions are also affected by this issue.
