Drowneds with tridents target players in creative after switching from survival

If you are in survival near a Drowned that has a trident and then switch to creative mode, the Drowned will sometimes still target you and start throwing tridents at you. Sometimes they only throw 1 or 2 tridents, sometimes they throw a lot more, it is quite inconsistent. It only happens at night (13000), and they will stop attacking if it becomes day time (1000). This does not happen with Drowned that have anything other than a trident.
