When autosize (a frame property) is enabled, then the (text) frame manages it's height/width based on the content such that all the text is visible. The user cannot decrease the height/width to be less than the content height/width, but the resize handles show up, and clicking and dragging is enabled, which shows a blue virtual resize frame. This patch adds UI feedback mechanism such that if the drag leads to some change in any dimention of the original frame, then the frame color will remain blue, otherwise it turns red.
