The Bug:

Amethyst crystals within amethyst geodes can generate floating.

Floating amethyst buds appeared upon amethyst geode's generation. In this case, the geode generated intersecting a mineshaft, so floating amethyst buds may be related to geodes generating within other structures.

Here is an example:

Seed: 8587948038190963789
Coordinates: /execute in minecraft:overworld run tp @s 5043.47 -49.00 150.71 -19.95 21.90

Steps to Reproduce:

1. Generate a world with the seed provided above and teleport to the given coordinates.
2. Look closely at the generation of amethyst crystals within the amethyst geode.
3. Take note as to whether or not amethyst crystals within amethyst geodes can generate floating.

Observed Behavior:

Amethyst crystals can generate floating.

Expected Behavior:

Amethyst crystals would not be able to generate floating.
