bug#8358: 24.0.50; `minibuffer-scroll-window' with active minibuffer: always *Completions*?

`with-output-to-temp-buffer' which displays the *Completions* buffer
sets `minibuffer-scroll-window' to the window showing *Completions*.
This happens _after_ running `completion-setup-hook' so your "foo"
doesn't really do what you expected.

Try doing

(add-hook 'temp-buffer-show-hook 'foo 'append)

instead.  Or write your own `temp-buffer-show-function'.
