On linux (guixsd), emacs master, I can see the tooltip but print nil


(setq tooltip-reuse-hidden-frame nil)
(progn
  (x-show-tip "this is a test"
		      (selected-frame)
              '((name . "tooltip1")
                (internal-border-width . 2)
                (left . 200)
                (top . 300)
                (width . 200)
                (height . 600)
                (border-width . 1)
                (no-special-glyphs . t))
              100 0 0)
  (dolist (frame (visible-frame-list))
    (when (frame-parameter frame 'tooltip)
      (princ (frame-parameters frame)))))
