Villagers in End detach from beds and workstations at reload

I have exported villagers into the End in order to make a village there.

Upon reloading the world the game, they seem to detach from workstations and beds, and then immediately reconnecting to beds/workstations, but not to the same ones.

I can make the villagers reconnect again by breaking/replacing beds/workstations. But they will not keep them once I exit the game.

This creates a chaotic village where all the villagers need to find beds/workstations upon game loading, also effectively eliminating the spawn of iron golems and cats until everyone is reconnected.

I have only observed this in End.

Attached picture shows an underground End village as shown immediately upon game load. Notice the green particles that reveal how the villagers have been disconnected and now connect again (but not necessarily to beds and workstations that are adjacent).

(I have also noticed that many villagers stand on the bed when morning comes. If the ceiling is only two blocks high, they suffocate because they get out standing on the bed instead of beside it.)

To reproduce, go to a stronghold in survival mode, finish the End portal. Push villagers into the End portal in order for them to appear in End when you teleport there. Bring lots of beds, workstations and needed materials. Teleport to the End.

In the End, make a village and put down beds and workstations. Notice how villagers connect to beds and workstations. To better observe whats happening, part the villagers from each other by walls, "trading hall" style.

Once all villages are connected to beds and workstations, save and exit the game world. Re-enter the game world.

Expected result: The villagers have kept their connections to beds and workstations.

Observed result: Villagers show green particles, revealing that they are reconnecting to beds/workstations and thereby that they have been disconnected from these. Also, villagers no longer are connected to the same beds/workstations, quickly resulting in angry particles above them, revealing that they cannot reach their connected beds/workstations.
