When MouseArea is touched via touch screen, previously hovered MouseArea's containsMouse flag doesn't get reset when another MouseArea is touched.
1. Run attached qt5touch.qml.
2. Using touch screen, touch 4 rectangles in order.
3. => After touching them several times, all four rectangles are in hovered state until mouse is clicked.
