After emacs -Q, evaluate this:

(defun my-test ()
   (interactive)
   (switch-to-buffer "*Test*")
   (kill-all-local-variables)
   (make-local-variable 'widget-example-repeat)
   (let ((inhibit-read-only t))
     (erase-buffer))
   (remove-overlays)
   (insert "TEST")
   (let ((ov (make-overlay (point-min) (point-max))))
     (overlay-put ov 'pointer 'hand))
   (let ((ov (make-overlay (point-min) (point-max))))
     (overlay-put ov 'pointer 'arrow)
     (overlay-put ov 'mouse-face 'shadow)
     (overlay-put ov 'priority 110))
   (insert "\nText without overlay"))

M-x my-test RET

Hover with the mouse the text "TEST", and move point to it (for example,
with M-<).  The pointer begins to change back and forth between arrow
and hand, staying as arrow most of the time.

This seems to be toolkit-dependant, since it doesn't happen on
