Thanks for the bug report but this is not a bug.
The login screen always exists separately on VT1 (Ctrl+Alt+F1) to your
desktop on VT2 (Ctrl+Alt+F2). And the desktop is not meant to lock
immediately. It should do after some period of time, but won't "if you
were listening a web radio on Firefox" because that's a normal means of
preventing the screen from locking.
** Changed in: gnome-shell (Ubuntu)
Status: New => Invalid
