### Bug Description

When selecting a //chunk and //regen 'ing it, the area is not correspondant to the world seed at all.

### Expected Behavior

Generate the correct area using the world's seed.

### Reproduction Steps

1. Load server with the above Paper, WorldEdit, WorldGuard versions, as well as latest Multiverse: https://github.com/Multiverse/Multiverse-Core/releases/tag/4.3.12
2. Use command /mv create testworld normal
3. Verify seed in game matches the seed in Multiverse config using /seed command
4. Go to any random chunk and select it with //chunk
5. Use //regen and notice it regenerates a completely different area.

### Anything Else?

Wondering if this has ever been fixed as I've noticed it occurring for a very long time (years) and there continue to be reports about it until this day. Example: https://github.com/EngineHub/WorldEdit/issues/1544 (2020, with latest reply this year in 2023). Would appreciate any help here. CC: @dumptruckman
