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.
