Entity activation Nether portal issues
Expected behavior
according to the wiki https://minecraft.fandom.com/zh/wiki/%E4%B8%8B%E7%95%8C%E4%BC%A0%E9%80%81%E9%97%A8?so=search
Most entities can teleport through Nether Portals, including various creatures (except Withers and Ender Dragons), ships, minecarts, projectiles, and item entities, but if one creature rides the other, neither creature can pass through the portal. Since only the player can make a portal spawn in another dimension, none of the entities mentioned above can pass through a portal that does not have an activated door in the corresponding dimension.
Observed/Actual behavior
when the entity passes through a nether portal in the world, a nether protal will be generated in the nether
Steps/models to reproduce
1.Create Nether portal 2.throw entity or let mobs go through it

Expected behavior like paper
Observed/Actual behavior entities active neither portal and in neither
The entity teleportation logic requires the entity to be removed from the current world. The portal logic requires that the portal search occurs asynchronously as the target region is not owned by the current thread. The end result is that in order to maintain the behavior that once an entity contacts a portal it is teleported, that the entity is first removed and then the portal search occurs. There isn't a sensible fallback to "the portal doesn't exist" other than to create it, as it does for players.
I understand that this isn't Vanilla, but that is the price to pay here for region threading.
