Minecarts become unlinked going through portals and carts left behind

[Flatkat]

When going through a nether portal only the first cart i am riding in goes through and any that are linked are left behind in the overworld.

Original issue from Linkart repo: constellation-mc#49

Did this work with non-player minecarts before 1.21?

Just tested and it doesn't work on versions prior to 1.21 with non-player minecarts either
