[MC-236879] Fish spawn in absurd amounts in underground waterfalls

Summary

I placed a water source over a big drop and got 3 stacks of fish (cod & salmon) in about 5 minutes. Fish rain from waterfalls. If it's relevant, this was under an ocean.

To reproduce

Generate a world with default settings and the seed 3220264758811034948 in 21w37a.
Go to -20 0 50 and place a water source block at the roof of the cave.
Wait at the bottom of the waterfall.

Might be a duplicate of MC-214829, but this one is talking more about fish dying consistently on underground waterfalls (like glow squids), which can often lead to lots of items laying around, causing lag.

Is this still an issue in 21w40a or later?

It isn't. Fish spawn high enough that they don't spawn in underground waterfalls anymore. I'd mark this as resolved.

Wait, was this reopened? The issue was fixed, because fish don't spawn this low underground anymore. The resolution is currently "Cannot Reproduce."
