Entity Documentation - minecraft:is_stackable

Allows instances of this entity to have vertical and horizontal collisions with each other. For a collision to occur, both instances must have a "minecraft:collision_box" component. Stackable behavior is closely related to collidable behavior. While the "minecraft:is_stackable" component describes how an entity interacts with others of its own kind, the "minecraft:is_collidable" component governs how other mobs interact with the component's owner.).
