I am not sure if this is really Works as Intended, but I decided to just report it.

The bug

Beds in Trial Chamber Intersections are reworked to generate with random colors since 1.21.2, which involves template pool trial_chambers/decor/bed.json. However, an inspection reveals that in the pool, the weight for pink_bed sub-structure is 1 instead of 3 (for the other colors), which means that pink beds generate less likely in intersections.

Steps to Reproduce

1. From vanilla datapack, retrieve data/minecraft/worldgen/template_pool/trial_chambers/decor/bed.json, the template pool file.
2. Inspect this definition file, especially the weights assigned to individual entries
3. Note that pink bed has a weight of 1 instead of 3

Technically also noticeable if you run a block distribution counter over many instances of worldgen, but that may be too complicated.
