(ert-deftest popup-test-two-tip ()
  (popup-test-with-temp-buffer
   (popup-tip "Foo\nBar" :nowait t)
   (save-excursion (insert "\n"))
   (popup-tip "Baz\nQux" :nowait t)
   (with-current-buffer (popup-test-helper-get-overlays-buffer)
     (let ((points1 (popup-test-helper-match-points '("Foo" "Bar")))
           (points2 (popup-test-helper-match-points '("Baz" "Qux"))))
       (should (popup-test-helper-same-all-p
                (popup-test-helper-points-to-columns points1)))
       (should (popup-test-helper-same-all-p
                (popup-test-helper-points-to-columns points2)))
       (should (eq (line-number-at-pos (car points2)) 2))
       (should (eq (line-number-at-pos (car points1)) 3))
       ))))
