Chunks become invisible when camera Y level is above 270 or below 0

[yezhiyi9670]

Describe the bug Many chunks become invisible when camera Y level is above 270 or below 0 due to broken culling.

Reproducibility

• [x] I reproduced this issue with as few other mods as possible installed.

To Reproduce

1. Open any world.
2. Change render distance to 16 or higher in order to make the issue obvious.
3. Get to high Y level by executing /tp @s ~ 270 ~.
4. Fly up by a little bit.
   ❎ The terrain below become suddenly invisible.
5. Get below 0 by executing /tp @s ~ -10 ~.
6. Fly around. ❎ Only the chunk above the player's position will show. There may be a chance that chunks flicker.

Technical Info It's found that the issue is gone if I void the isVisibleFromAnyOrigin method in AbstractRenderChunk.java.

    public boolean isVisibleFromAnyOrigin(Direction direction) {
        // return (visibleDirections & (1 << direction.ordinal())) != 0;
        return true;
    }
