Qml TableView scrollbar

CC90202

Dear All,
I've tried to install a very simple program on my windows 10 touch display device:

import QtQuick 2.15
import QtQuick.Window 2.0
import QtQuick.Controls 1.4
import QtQuick.Controls 2.4
import QtQuick.Controls.Styles 1.4
import QtQml.Models 2.2

Window {
    width: 641
    height: 480
    visible: true
    title: qsTr("Hello World")
    Rectangle {
        width: 640
        height: 200
        anchors.fill: parent
        TableView {
            id: tv
            horizontalScrollBarPolicy: Qt.ScrollBarAlwaysOff
            verticalScrollBarPolicy: Qt.ScrollBarAlwaysOn

            TableViewColumn {
                role: "title"
                title: "Title"
                width: 100
            }
            TableViewColumn {
                role: "author"
                title: "Author"
                width: 200
            }
            model: libraryModel1


            ListModel {
                id: libraryModel1
                ListElement {
                    title: "Title 1"
                    author: "Topo Gigio"
                }
                ListElement {
                    title: "Title 2"
                    author: "Paperino"
                }
                ListElement {
                    title: "Title 3"
                    author: "Qui Quo Qua"
                }
                ListElement {
                    title: "Title 1"
                    author: "Topo Gigio"
                }
                ListElement {
                    title: "Title 2"
                    author: "Paperino"
                }
                ListElement {
                    title: "Title 3"
                    author: "Qui Quo Qua"
                }
                ListElement {
                    title: "Title 1"
                    author: "Topo Gigio"
                }
                ListElement {
                    title: "Title 2"
                    author: "Paperino"
                }
                ListElement {
                    title: "Title 3"
                    author: "Qui Quo Qua"
                }
                ListElement {
                    title: "Title 1"
                    author: "Topo Gigio"
                }
                ListElement {
                    title: "Title 2"
                    author: "Paperino"
                }
                ListElement {
                    title: "Title 3"
                    author: "Qui Quo Qua"
                }
            }
        }
    }
}

I've found a strange behaviour: the scrollbar doesn't accept touch events. It works only with the mouse.
Does anydoby face this problem?
What you suggest to solve it in order to get touch events on the handle ?

Thank you
Cristiano
