Villagers either disappear or end up clipping through walls after teleporting through portals.

I use minecarts to teleport villagers through portals.   Oftentimes my portals have a backwall on them, so that villagers cannot come out the "wrong" side of a portal.     The way I send them is via Minecart.   I capture them in a cart, roll them down a rail to the portal, and use three powered rails to yeet them all the way into the portal, up against the backwall.  Then I break their minecart and they instantly teleport.  Once on the other side, there is a rail and a minecart waiting so that the villager easily gets recaptured in a new cart, then I can roll them to wherever I want them to go (like a raid farm, for example).   

This technique worked through all versions  of 1.18.   

In 1.19, on the other side of the portal, I find the villagers are either stuck in nearby walls and suffocate, or they never appear at all.    I have tried this at two different portals.   At one portal, the villagers routinely get stuck in the wallspace behind the target portal.   At another portal (my raid farm), the villagers never appear (I made four attempts).   

This occurs on the xBox, and I believe the Switch as well.  I play on both.   It is repeatable on both systems, even after system restarts.
