Pointer Handlers reuse QObject::parent() for parentItem(). A handler should not be instantiated in C++ with no parent, because it could leak at shutdown if left in that state. But now we have QQuickPointerHandler::setParentItem(), which hides the details of adding it to ExtraData::pointerHandlers, so we no longer need to do that explicitly here; and it doesn't seem harmful to otherwise allow the handlers' QObject::parent to be the SelectionRectangle itself.
