Adorner not refreshing after pageItem move/resize

Hi

Following the FrameLabel/FrameLabelUI SDK example, I have added an adorner to a pageitem (basically I add string "test" at the bottom right corner of the page item (outside the pageitem bound).

However, when i move the page item or resize it, the adorned string "test" does not always move with the item and gets stuck at its original location. Only when i do a refresh of the page, that the adorned string "test" move to the boundary of the pageitem (bottom right corner). I am wondering if there is any way to avoid this situation so that anytime the object moves/resizes, the adorned text also aligns with the object
