Expected behavior: Azalea Trees generated over any terrain have a system of rooted dirt which continues down to a lush cave.
Observed behavior: The root system of Azalea Trees that generate over sandy environments (specifically observed on a snowy beach, but might generalize to beaches, deserts, and badlands) replace sand but not sandstone during world generation.
