Warped wart blocks do not generate in the floor of the warped forest biome

In the Warped Forest, Warped Wart Blocks are supposed to occasionally generate in the floor among the nylium, as could originally be seen on Java Edition (but no longer happens in 1.18, for both Warped and Crimson Forests).

How to reproduce:

Seed: 90907959

Nether coordinates: 246, 62, -14

Note that Nether Wart Blocks are still generating in the floor of Crimson Forests just fine, despite the fact that they no longer do in Java Edition.
