[MC-130788] "Basin" structure is flooded since part of it generates below sea level

Might be a tough bug to fix but this naturally generated "basin" structure ended up with part of it below sea level so the chunk populator flooded it.

Tip: Output of /seed is copiable and F3+C copies coords into clipboard, that helps us a lot!

Probably relates to MC-130584 "When a structure loads, blocks that can be waterlogged are filled with water when placed in water"

Hm, a Basin is neither a structure nor are there waterloggable blocks.

I noticed such patterns rarely, but is this intentional? To me it seems like a bug in the world generation.
