Catching a fish/axolotl in a bucket in Creative mode does not grant advancements

In Creative mode, catching an axolotl in the bucket does not grant "The Cutest Predator" advancement, and catching a fish in a bucket does not grant the "Tactical Fishing" advancement. This seems like an inconsistency, because with recent changes, the player does obtain the items (bucket of axolotl, bucket of fish).
