Can't tame horses in 15w41b

Put the summary of the bug you're having here

So, I was playing with a freind on a private 15w41b snapshot server that I had created and had ventured on a journey for some coco beans.

At this point I see some horses that I thought would be nice to travel with and get on one that I like the looks of.

After 5 minuets of sitting, the horse was still not tamed. It didn't even buck me off. It just went around doing its usual business. I had a saddle with me and had tried to put it on the horse over time but it never let me do it. The hearts never appeared or anything. I went into creative and tried spawning new horses in and taming them and feeding the fully grown horses but none of it seemed to work.

At this point I thought it was server side so I went into a single player world and tried it out but the out come was the same.

That is all that I can think of to do, but if you have any more input you need me to provide, I'll happily oblige.
