Zombies and skeleton are trapped in a closed door

zombies and skeletons are trapped in closed doors

skeleton is stuck but he can move as long as there is a door on the side but zombies can only get stuck can not move and move forward (actually villagers can also get stuck but they can still open the door) (but this is good bug i can't trap they and gives they name ) (creeper ?? I have not tried H3H3 I forgot)
