The Bug
Boggeds can spawn in caves under Mangrove Swamps and Swamps. This is inconsistent with Husks and Strays were they cannot spawn in caves.
Reproduce
Go to a Swamp or Mangrove Swamp
Do the command /effect give @e[type=minecraft:bogged] minecraft:glowing infinite
Observed Result
Boggeds spawned in the caves
Expected Result
Boggds wouldn't spawn in caves

I wish "underground" or "surface" was in the description somewhere, I searched for those terms and could not find it, and specifying "caves" isn't really helpful as their spawning isn't exclusive to caves, it's any underground area in the swamp biomes.
I guess now that my duplicate uses those terms and links here, it's fine now
Also relates to MCPE-178928.
Can confirm.
Though, one thing to note is that the changelog says that they simply spawn in swamp biomes, and doesn't clarify any min/max height for it. In the screenshots, the caves you're in are still swamp biomes.
