Bug 456579

SUMMARY
using a [MultiPointTouchArea](https://doc.qt.io/qt-5/qml-qtquick-multipointtoucharea.html) inside a normal QtQuick.Window works well both with a touchscreen and with a mouse, but if it placed as a child of a Kirigami.Page it doesn't work anymore with the touchscreen, while working well with a mouse. The touchscreen gesture is stopped after about half a second.


STEPS TO REPRODUCE
1. use this simple code on a touchscreen:
```
import QtQuick 2.15
import org.kde.kirigami 2.13 as Kirigami

Kirigami.ApplicationWindow {
	id: window
	title: i18nc("@title:window", "Hello World")

	pageStack.initialPage: Kirigami.Page {
		Rectangle{
			color: "red"
			anchors.fill: parent
			Rectangle{
				id: rectangle
				color: "green"
			}
			MultiPointTouchArea{
				anchors.fill: parent
				touchPoints: [
					TouchPoint { id: point1 }
				]
				onUpdated: {
					rectangle.height = point1.y
					rectangle.width = point1.x
				}
			}
		}
	}
}
```
2. try to drag the screen with the mouse and then with the touchscreen

OBSERVED RESULT
with the mouse the green rectangle's size is correctly updated, while with the touchscreen it stops moving after a little amount of time

EXPECTED RESULT
it behaves with the touchscreen as it does with the mouse, without stopping
