The bug

Splash water bottle can extinguish the fire, soul fire, campfire, soul campfire, candle or cake with candle outside the world border. This is unexpected behavior, since blocks should not be able to be destroyed or interacted with (for example, arrows can't destroy chorus flowers or decorated pots) outside the world border.
