Repro steps:
emacs -Q
C-h b
click function name link
click back
expected:
go back to the C-h b keymap listing
acutal
in echo area: "Current buffer is not in Help mode"
the help buffer does no change.
The problem does not always happen, but it seems consistent on the first try in
a
fresh emacs. Toggling debug on error, gives this trace:
Debugger entered--Lisp error: (error "Current buffer is not in Help mode")
