MouseArea not updates pressed after a system move

/* MouseArea not updates pressed property after requesting a system move
 * - After the mouse button (or equivalent) is released, pressed is still true.
 * - Then the MouseArea consumes any input event until the mouse button is released again.
 * - So you cannot make two consecutive moves, or any other action until you click and release again.
