How can you reproduce that?  Here the tooltip disappears immediately
when moving the mouse from the tool bar button to the frame border.

You mean that the help_echo_string built by

      if (cursor != FRAME_X_OUTPUT (f)->nontext_cursor)
        {
          /* Do we really want a help echo here?  */
          help_echo_string = build_string ("drag-mouse-1: resize frame");
          goto set_cursor;

should be immediately erased when we "have a window" and be left as is
when we just "have a frame"?  Or am I missing something else?
