PC [BUG] Horse can be ridden through stone fences

[Polo3cat]

When ridding alongisde a stone fence it is possible to go through it and cross to the other side.

Steps to reproduce

1. While riding the horse, move as close as possible to the fence.
2. Move up or down, parallel to the fence.
3. While holding the up or down key (W, or S in my computer), try moving towards the fence (pressing the move left or right key, A or D in my computer).
4. The horse will clip into the wall.

After clipping into the fence, collision will be ignored until you move away from the fence and try going through it again (at least approaching it perpendicularly).
Clipping happens for a particular fence, other fences will still have collision. For example, having fences going top to bottom and clipping trough the 4th one will ignore collision on that one, but fences 3 and 5 will still have collision.

This is a known issue that can occur on all platforms. My understanding is that it's unlikely to be fixed, as the behavior is inherent to how fences and horses are coded.
