My understanding of the situation so far is: - The `(with-output-to-temp-buffer "*Completions*" ...)' form in minibuffer-completion-help results in `display-buffer' being called with `display-buffer-mark-dedicated' bound to `soft'. - The `(and pop-up-windows ...)' clause of `display-buffer' is evaluated*, and calls `(set-window-dedicated-p window-to-use 'soft)'. - However, the `window--display-buffer-2' call then calls `set-window-buffer', which sets `w->dedicated = Qnil'. - Later, when `(bury-buffer)' is called to hide the minibuffer help, it sees the window is not dedicated, so it switches to a new buffer instead of killing the window. (* I haven't bothered yet to look into why that particular clause is evaluated, but I don't think it matters; it's just the one that stepping through the code took me to.)
