[MC-242058] Chunks not blending when in snapshot 21w38a to any of the Pre-releases

Chunks have no blending at all.

I have a taken worlds from 21w38a and tried using all 5 pre-releases to blend them. None of them blended, giving harsh borders on each chunk boundary.

How to replicate: Create a world in 21w38a. Then reload the game and play in Pre-5 and fly to the edge of the loaded area. Once there you will see the chunk borders and lack of blending.

See MC-237935.

There's no blending when upgrading from a 1.18 dev version to another 1.18 dev version. Only when upgrading from 1.17.1 or below.
