Baby horses not tameable

What I expected to happen was for me to be able to tame a baby horse that i grew.

What actually happened was that everytime i would right click, instead of sitting on the horse i was teleported beside it instead. my player wouldn't even get on the horse.

Steps to Reproduce:
1. Tame 2 horses
2. Breed both horses together to make a baby horse
3. Grow the baby horse
4. Try to tame it
5. Bug triggers
