Still travelling at an abnorally high speed when following your boat on 1.15-preX

Still happens, 1.15. While traveling with a boat a dolphin could travel with hyper speed around you.

Happened to me when I found the dolphin for the first time.

Isn't that just how dolphins were designed?

I think they're supposed to do something similar around players in boats but what's happening right now is ridiculous, they move so fast they just go off the world and de-load themselves if the ocean is big enough. It's pretty funny to watch though, makes no sense.

Still in 20w07a
