wrong local position of QNativeGestureEvent inside QQuickWidget

1) add QQuickWidget to the MainWindow
2) implement "event" method to catch QNativeGestureEvent
3) call QNativeGestureEvent::pos();

expected result: pos is the same as for QMouseEvent for this widget
actual result: local pos is not in QQuickWidget coordinates

example application output:
mouse pressed on pos QPoint(5,3)
native gesture pos QPoint(232,120)

details:
call QQuickWidget::mapFromGlobal(QNativeGestureEvent::globalPos) works as expected
