[MC-227607] Lily pads generate on blocks within structures

I saw a lilypad generating on a block, which i think doesn't work as intended.

Seed: -2673931441407680092
Coordinates: /execute in minecraft:overworld run tp @s -116236.51 61.88 3907.52 -565.53 22.00

The lily pad wouldn't generate on blocks that aren't ice or water

Can confirm on 1.17 Release Candidate 1 with slightly different coordinates. Clones MC-113898.

Okay

It could be beneficial to rename the issue so that "structure blocks" is not confused with the actual structure blocks.

Yes, that confused me as well, before I clicked on it. I'd recommend changing that to, "blocks from structures" or something like that.

I suspect this also affects ruined portals based on other reports, but I wasn't able to find an example seed.

Might relate to MC-140727.
