Horse stays in the air after jumping and getting off

Horse stays in the air after jumping and getting off

What I expected to happen was...:
After getting of the horse that it would go back to the ground

What actually happened was...:
after getting of the horse it stayed in a jumping animation

Steps to Reproduce:
1. First get on a taimed horse
2. Then jump with the horse and whilst jumping get of the horse
3. Now you see the horse stuck in the jumping animation and it will reset if you get on it again
