The touch pointer capture is never released when you swipe an item in order to show its swipe content. Because the touch capture is never released, the pointer released action is never fired and the drag/drop operation cannot finish. This leads to glitches in the item. Clicking in swipe content can make it disappear. Also, if you are on a device that support both mouse and touch, you can notice the issue by swiping with touch and then mouse move. The mouse/touch device is captured and you will see that item moves on mouse move even if the left button is not pressed.
