The problem is not that VIEW-CORNERS returns the wrong values.
The problem is that you're calling it after setting the ccl::draw-outline
slot to NIL. The following method does the right thing. If you find it too
flashy, I can make a version that flashes less (but you try it first, please):

(defmethod set-draw-outline ((e ccl::basic-editable-text-dialog-item)
                             new-outline)
  (let ((new-outline (not (null new-outline)))
        (old-outline (not (null (slot-value e 'ccl::draw-outline)))))
    (unless (eq old-outline new-outline)
      (without-interrupts
       (when old-outline
         (invalidate-view e t))         ; erase the outline
       (setf (slot-value e 'ccl::draw-outline) new-outline)
       (when old-outline
         (validate-view e))             ; don't erase the text
       (invalidate-view e)))            ; redraw. This flashes a little.
