Like title says, when you dismount a horse whilst its inventory is open, it doesn't close.

Ok, but how do you dismount while the horse inventory is open ?
LSHIFT doesn't work while the horse inventory is open.
I'm not sure how you dismounted with the inventory open, but since you don't need to ride to access the inventory, I don't consider this as a bug.
How dow you mount a horse while the inventory is open or how do you open it while mounted ?
