I can confirm, and got some possibly useful information from testing. The bug appeared in snapshot 20w22a. It seems that by using the process listed by the reporter, the player can freely walk around and interact as if they were moving, but mobs will still attack the player's original position (and deal damage) if they see it instead of the player's apparent position, and commands use the player's original position as well.

Edit for clarification: the bug appears in versions from ** 20w22a to 1.16.3, not just in 20w22a.

Sometimes when you are in a boat that is riding a enderman and look down to the enderman head, he will start teleporting and you will be thrown out of the boat, if you are in a cave you will start suffocating, because you are in the boat with the head in a block, and If you hit any mob, the mob will start walking to the boat and start attacking you, press shift and you will be in the boat(out of it).

Can this still be reproduced in 21w05 or later?
