Snap to object in Flex block

We've added snapping elements to other objects while freely arranging elements in a Flex block or an ordinary block. Element snapping occurs when it gets closer than 5 px to another freely arranged element, a block's boundary or center. At the same time, a red line will highlight the border to which snapping occurred. Also, snapping doesn't work when moving elements using keyboard arrows. It is convenient if you need to place an element less than 5 px away from the boundary to which snapping may occur.
