repeatedly teleported up causing glitchy behaviour.

Additional Details

https://youtu.be/W79ipjmR2YQ video showing the issue. You may need to skip around or fast forward. Because I wanted to show it happening across different mobs and demonstrate that it happens on standard and non standard dimension scales it's a bit long and I don't want to edit and render the video.

I think this is probably an issue with how immersive portals mount teleportation is handled.

I've also submitted an issue for immersive portals on this one as vanilla mechanics like minecarts also cause buggy behavior when falling through portals. iPortalTeam/ImmersivePortalsModForNeo#17
