Wires Docking - Docked shapes must update their location as the parent's one is resized

Once resizing a wires shape, if it contains any "docked" one, the docked shape still remains at same location, rather than the shape's bounds that are different as from the resize. On the other hand, the docked shaped is already "docked" to the parent in memory, but from the UI both shapes are not docked. This causes lot of confusion to the user.
