Occasional desync when trying to enter/exit a boat while the server is lagging

When entering a boat when sitting in another boat while the server is lagging, it is possible that a client-server-desync occurs, where the client is outside of the boat while the server still considers the player to be inside of it.

To reproduce

  1. Place a lot of boats in the same place (e.g. activate a repeating command block with the command summon boat ~ ~0.5 ~ for a second)

  2. Cause server lag, e.g. by setting /gamerule randomTickSpeed to a high number (mspt should be above 50)

  3. Right-click the boats repeatedly until you are no longer able to enter them
    → ❌ Desync

  4. Walk away

  5. Try to place a block
    → It disappears

  6. Press shift
    → You're teleported back to the boats
