Floating water caves in caves under the ocean

Waterlogged caves become floating water tunnels when they intersect with open-air caves/ravines.

What I expected to happen was...:
The ravine/cave to become waterlogged.

What actually happened was...:
A strange bug causing strange but interesting floating water tunnels.

Steps to Reproduce:
1. Find a world where a waterlogged cave intersects with a ravine or cave, e.g. -8392751900383477890
2. Look around, e.g. -629 27 78
3. Contemplate life.

It's not just ravines. It affects all caves.

Example: Seed=1

  • Coords=-210, 11, 141.

  • Coords=-317, 11, 133.

They appear to be quite common. (The above coords are below an ocean biome.)

Came across this as well.

Can confirm.

Judging by the screenshot provided by @unknown, I've managed to encounter something similar in 21w19a, therefore I do not believe that this issue has been fixed in this version. You can see this through the use of the following seed + coordinates.

Seed: 7322373498288204599
Coordinates: /execute in minecraft:overworld run tp @s 31141.57 22.05 -1131.92 147.58 25.48
