Horses (and possibly other rideable mobs) facing North on First Person

Horses (or any rideable mob it seems) immediately face South when right-clicked on First Person. This glitch can also be replicated by using Toggle Perspective, and rideable mobs WILL face South once you change your perspective back to First Person.

I do sincerely apologize if this ends up being a duplicate. I'm currently new to the whole bug tracker report thing.
