Liquids should generate already flown, like they do in 1.12.2.
That is working as intended now. See MC-124911.
This is not a bug. The bug where random ticks would effect liquids was fixed, leading to this. This is incorrect world generation. Liquids should generate already flown, like they do in 1.12.2. That is the bug, not that liquids are not effected by random ticks.
