Terrain blending of old worlds places dirt and stone on icebergs in frozen oceans

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 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.

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