Switch to new emacs-lisp-mode buffer and insert :

(defun foo ()

M-x outline-minor-mode
M-x hide-entry

Then undo as much as possible, i.e. until buffer is empty again.
Now, after a C-g and a redo, the old overlay conceals the just
undone change and it looks like this:


There seems to be no reason for defunct overlays to hang around,
so make them evaporate.
