Oceans cannot spawn land animals on dry grass

Steps to reproduce

1. Find any ocean biome.

2. Make a large grass block platform above the water.

3. Set time to noon and turn off daylight cycle.

4. Fly up 30 blocks above the platform and wait for spawns.

Expected results

Animals spawn on the grass.

Observed results

Nothing spawns on the grass.

Code analysis

None of the ocean biome definitions in the vanilla behavior pack have the “animal” tag, which is necessary to spawn cows, sheep, pigs, and chickens. These biomes do have the warm/cold farm animal variant tags that were ported from Java despite having no functionality in Bedrock, which seems to indicate that animals are intended to spawn. The animal tag may have been removed when the Java spawn variant tags were added.
