When an old world is upgraded, and that world has icebergs at the edge of the blended area in a frozen ocean biome, the icebergs get dirt and stone placed next to them.
To reproduce:
1.Make a creative world in 1.17.1 with seed 16. Save without moving.
2.Load this world in 1.18-pre1 (or version being tested).
3.Fly around the edges of the world around the frozen oceans. -> Icebergs have stone and dirt placed on them at the blended edge.
Attached screenshot was taken with seed 16 near -97 -270.

I tested this in 1.18 release candidate 3 and it still occurs. This makes chunk borders quite obvious in frozen oceans.

I can confirm with other pictures as well, this seems like the same sort of problem as 1.11 worlds loading surface blocks instead of leaves. I updated this world from 1.17.1 to Pre-release 1.
