When you exit a boat it disappears or rushes at you from behind

Steps to reproduce

1. Ride a boat some distance.
2. Exit the boat and look back.

Expected result

You see the boat sitting where you got out of it.

Actual result

Updated for 1.18.0:

• If you travelled a distance greater than your render distance setting from where you embarked, the boat usually disappears. The boat will reappear at the spot where you disembarked if you
  • Move > 70 blocks horizontally from the disembark location (entity render distance) and then back.
  • Reload the world.
• If the boat does not disappear, it appears to teleport backward to the location where you embarked, and then it flies rapidly in a straight line to the point where you disembarked.
• Mobs riding the boat have often been seen to teleport around while the boat remains invisible. This is not a separate bug, just a consequence of the boat being in an abnormal state.

Workarounds:

• You can shoot the invisible boat with a sufficiently strong bow and it will drop. You only have to aim to the place where you exited the boat.

• For people playing on worlds with cheats/commands enabled.
  Make sure you have one and only one boat (visible or not, where it is supposed to be) within a distance of 20 blocks:

  /ride @s start_riding @e[type=boat,r=20]
  

  And, to do it for another player:

  /execute Player_Name ride Player_Name start_riding @e[type=boat,r=20]
