Description

Certain world seeds (where the spawn point is inside a Grove biome) result in spawn points on top of or inside powder snow, instantly trapping the newly-spawned survival player.

To reproduce

There are likely many seeds to cause this, I found the following one: 3999628195817584576
Please consider that the spawn point is slightly different upon each world creation. So expect to re-create the world a few times. In my testing, I observed the bug occur 6 out of 17 times.

Expected behaviour

Just like it is the case with water lakes or oceans, the world generator should move the spawn point in order to not place the player on top of or inside powder snow.
