The "Game Mode" and "Allow Commands" buttons in the Open to LAN screen do not affect the host

Thank you for helping us improve Minecraft! We saved your files:

I tried some things with a friend putting creative and allow commands:
other players joining still get the permissions and new gamemode.
The other player have access to debug commands but:
- there is no /op to give permissions to the world host
- /defaultgamemode will change the world host’s gamemode and not the other player’s gamemode (even /defaultgamemode creative when it was previously set by the open to lan and not changed since changed the world host’s gamemode to creative and then setting it back to survival changed only the host back to survival)

Thank you for your report!
