When entering spectator mode while standing on the ground, the player moves down by a bit. This is related to
MC-146582, as it is considered a parity issue as well.
Steps to Reproduce
- Stand on the ground.
- Make sure the show coordinates game rule is on and take note of your Y coordinate.
- Use /gamemode spectator to switch into spectator mode.
The player stays on the same Y coordinate.
The player Y coordinate position is lowered when switching to spectator mode.
