Caves and ravines near the nether roof have flat ceilings

The Bug:

Near the top of the nether at y level 121, cave carvers always get cut off, resulting in caves and ravines having flat ceilings.

Here is an example:

Seed: 1692907036
Coordinates: /execute in minecraft:the_nether run tp @s -207.04 114.23 412.72 105.38 -46.64

Steps to Reproduce:

  1. Generate a world with the seed provided above and teleport to the given coordinates.

  2. Look closely at the ceiling of the cave/ravine.

  3. Take note as to whether or not caves and ravines near the nether roof have flat ceilings.

Observed Behavior:

Caves and ravines near the nether roof have flat ceilings.

Expected Behavior:

Caves and ravines near the nether roof would not have flat ceilings.

Can confirm.

Also, kind of unrelated, they appear to generate in different places as before, since I created the same seed and went to the nether both in 1.17.1 and 21w41a and there were caves in the snapshot where in the release there weren't any
