When kicking yourself out of a world NOT opened to LAN, the game brings you to the server list screen.
Expectations:
Singleplayer kick: World list screen
LAN world kick(When you're owner of the world): World list screen
LAN world kick(When you joined via server screen): Server list screen
Server kick: Server list screen
How to reproduce:
Create/Join an existing singleplayer world with cheats on
Type in chat /kick @s
Notice you'll be brought to server list screen
It works in every version that has /kick command, not only 1.17

(I'll be attaching a video tomorrow showcasing it)
