When I put an entity (for example a cat) in a boat, that then I go in this boat with it into the nether portal and that I leave the boat (leaving only the entity in the boat and in the nether portal), when I break the boat, the entity cannot go through a nether portal. This bug affects Minecraft Server 1.14.4 (i tried in a non-server version and the entity goes through the portal)
