This is the case that I meant:

 emacs -Q

 M-x info               ;; don't type RET
 C-h f RET              ;; describe function 'info'
 C-x o C-x o            ;; switch to Help window
 <tab> <return>         ;; visit info.el from help link
 C-x o C-x o            ;; switch to minibuffer
 C-g                    ;; exit minibuffer
