A scale resize measured its drop-point correction while the gesture's own translation was still applied, but the position commit adds that correction onto the element's PRE-gesture position, which it reads from the gesture's base attributes. The two disagreed by the whole drag distance, so the commit persisted a position a drag-length from where the element was dropped: it held the drop point for one frame and then slid off. Move the element back to that base before measuring, so the residual and the commit share one origin. For an element whose position is a static hold that usually means no correction at all, which is the right answer: scaling about the centre already leaves it on the drop point.
