Animals often won't get out of water when being led by wheat / carrot / potato / seeds

What I expected to happen was...:
The animals come up onto land and continue following the player

What actually happened was...:
The animals came to the water's edge and stopped moving. They still looked at the player.

Steps to Reproduce:
1. Create pool of water source blocks
2. Spawn one or more cows inside of pool
3. Hold wheat and wait for the cow(s) to begin to follow you
4. Back away slowly from the pool
