Perspective Reset While Riding Horse

While riding a horse in thirdperson, if you ride through a solid block your perspective will be set back to first person. Works in both Survival and Creative.

Steps to Reproduce:
1. Get a horse
2. Put a block two spaces above the ground
3. Ride the horse through the block in thirdperson and reset your perspective.
