When I try to tame a horse, and after I get on it, this one doesn't reject me and I can't put a saddle on it.

What I expected to happen was to tame it by giving it for exemple apples and get the littles hearts which means I tame it.

What actually happened was absolutely nothing

Steps to Reproduce:
1. Find or spawn a horse
2. give it food for tame it
3. get on it and wait... nothing happens. Normally the horse reject you and you must repeat all for finelly tame it. Now it does not reject you, so you can't tame it.
