Entitys act like a magnet to a fishing rod

Cast a rod nearby an entity. If it is close enough, the bobber will go to the animal, even if it would have not hit it. Tested with sheep, cows, creepers, item frames, armor stands, and villagers. In the screenshots, you can see that I would have not hit the sheep, but I did. This happens even if the fishing bobber's hitbox and the entity's hitbox don't touch.
