Research direction
The issue names no files, tests, or entry points. Start by reproducing the desynchronization while riding a minecart through an end gateway on Paper 1.16.5, then trace the portal transfer and client entity updates. Done means the player and minecart remain synchronized, the minecart is visible, and the player can look around, move, or dismount.
