Noise caves can try to generate at any height they want

The bug

Starting with 21w06a, noise caves can generate at any height they want, which causes some strange effects. For example, the mountains are all broken up now because a bunch of noise caves just cut right through them. Normal caves fail to generate if they are exposed completely and have almost no walls. But these new ones (and sometimes geodes too) can generate however they want, making weird random holes everywhere.

Default world. Seed: -8610962999447939582 Cords:-206.13 77.86 -99.16. Look down. You will see these weird holes below you that generated for no reason.

On the same world at 182.47 97.34 -327.08, you will see a mountain with big holes in it as well.

Based on my findings, caves don't generate in superflat worlds.
