Horse foals dying

I have the latest ios update and latest minecraft update and ive noticed on mcpe theres a glitch where horse foals either glich through the walls or the die in them depending on the materials

How to preform the glitch: push a horse foal into a fence or wall and you will see it slide right through it or else die inside it

Its hard to take a screenshot on a phone because the horse foals move around so much and die in the process of trying to take a screenshot
