Jigsaw Structures With Heightmap Projection of World Surface Generate on Ocean Floor

I am creating a structure that generates on the ocean surface with the Jigsaw Structures Experiment. However, when I set the jigsaw's heightmap_projection to world_surface, it generates on the ocean floor.

Taking what I can from the very incomplete docs, this should generate it on the ocean surface. In addition, there is a separate heightmap_projection for ocean_floor, so it makes sense that world_surface would place it on the top of the ocean.

Steps to Reproduce:

  1. Attach mcpack to a Minecraft Preview world with Data-Driven Jigsaw Structures enabled.

  2. Locate structure ( /locate structure httyd:dragon_hunter_ship )

  3. Notice structure is nearly always on the ocean floor

Observed Results:

The structure is on the highest solid block.

Expected Results:

The structure should be on the highest non-air block, which is water.

I just attached the add-on to the files.

After further testing, I have discovered a possible workaround for this specific use case.

Typing in "/place structure httyd:dragon_hunter_ship ~ 63 ~ true" (true means ignore start_height) will place the structure at a specific location. Being able to set a specific xyz value in the jigsaw file, instead of a start_height and heightmap_projection, could open up the ability for floating structures that are based on coordinates, not world generation.

This is not an issue in the latest Preview version, 1.21.90.27. I’m not sure which version it was originally fixed in.
