Beaches can generate next to deserts if another biome borders a desert near a coast

If a desert is near a coast, then the coastline is still a desert instead of a beach. However if another biome borders that desert which is near coast, then it technically makes sense for the coastline of that new biome to be beach, resulting in the beach and the desert touching.

In my screenshot, the orange colder frogs are in the beach, and the tropical white frogs are in the desert.
