"terrain_matching" jigsaw pieces overlap features and jigsaw structures

When finding a custom jigsaw structure naturally in the world, there is a chance that the structure’s terrain_matching pieces will overlap features, such as trees, and other jigsaw structures/pieces, like buildings in this structure.

I have attached a screenshot and a demo pack to reproduce this issue. Use the latest preview.
1. Create a world using this seed: -1127587711546760178
2. Add the behavior pack to the world, enable the jigsaw experiment, and create the world
3. Use this command: /tp 1760 120 5456
4. You will be teleported to a custom jigsaw structure where this issue occurs.

I also added additional screenshots from a different seed, and they do not have the Preview’s debug text at the top. The screenshot with the debug text, is the seed above.
