The Bug:

Sugar cane can generate next to ice.

Ice is an invalid block for sugar cane to generate next to. Because of this, block updates cause the sugar cane to be destroyed and drop on the ground.

Here is an example:

Seed: 1359968930092793278
Coordinates: /execute in minecraft:overworld run tp @s 254.71 63.00 6.22 -220.03 17.55

Steps to Reproduce:

1. Generate a world with the seed provided above and teleport to the given coordinates.
2. Look closely at the sugar cane and its nearby surroundings.
3. Take note as to whether or not sugar cane can generate next to ice.

Observed Behavior:

Sugar cane can generate next to ice.

Expected Behavior:

Sugar cane would not be able to generate next to ice.

Potential Fix:

Removing sugar cane from the frozen river/snowy beach/snowy plains generation.
