[MC-214288] Player does not spawn on the surface of the world when min

I've done a code analysis for one of my issues (MC-217802) using the mojang obfusication maps:

//net.minecraft.world.level.levelgen.flat.FlatLevelGeneratorSettings

public int getMinBuildHeight() {
  return 0;
}
    
public int getHeight() {
  return 256;
}

This hardcoding of getMinBuildHeight() and getHeight() results in this bug
