Yet, that's what `resize_mini_window` does for all mini-windows
regardless of it's an echo-area or not.

Also, my patch shouldn't affect whether we "see the end of the text", so
maybe I just don't understand what you're referring to.

I thought the test of `scroll_minibuffer_conservative` played this role.
