                }
            }
        ]
    }
}```

when a player is using this it does give the movement speed in water even tho the player is not in water, Is there something about location_changed where it only checks the location based predicates? But soul_sand does use it?

I feel like I am missing something very small but it is driving me crazy

Wiki does not tell anything against my use case
