Being disconnected/kicked from singleplayer returns you to server list instead of world list

If you spam enough in your singleplayer world (an easy way is to hold a letter key and enter at the same time while in a bed), you will get kicked for "disconnect.spam" and then sent to the server list instead of your worlds list or the main menu. I'm not even sure if you're supposed to get kicked from spam while in singleplayer; that may be another bug entirely.
