Mouse used within MultiPointTouchArea

Problem description

If I use a mouse inside MultiPointTouchArea component, every mouse press is evaulated as gesture and gesture signal is emitted (except area aroud [0, 0] point relatively to MPTA).

This is happening, because gesture startX and startY is always 0.

import QtQuick 2.9
import QtQuick.Window 2.2

Window {
    visible: true

    id: root
    width: 1406; height: 536
    
    MultiPointTouchArea {
        id: touchArea

        anchors.fill: parent

        onGestureStarted: {
            console.log(gesture.touchPoints[0].startX, gesture.touchPoints[0].startX, gesture.touchPoints[0].x, gesture.touchPoints[0].y)
        }
    }
}

If I connect touch display and use touch, the startX and startY is changing as expected. (it contains the coordinates of the first touch)
