ScrollView in ListView delegate: can't scroll in Qt6 build

RickS

I have a ScrollView into a ListView delegate. The ScrollView is supposed to include a long text that can be vertically scrolled.

import QtQuick 2.15
import QtQuick.Window 2.15
import QtQuick.Controls 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Scroll Test")

    ListView {
        anchors.fill: parent
        model: 5
        delegate: Rectangle {
            id: rectDelegateId
            border.color: "blue"
            width: parent.width
            height: parent.height/5
            Rectangle {
                id: scrollRect
                width: rectDelegateId.width/2
                height: parent.height
                border.color: "black"
                color: "lightblue"
                ScrollView {
                    clip: true
                    anchors.fill: parent
                    Text {
                        text: "A1\nA2\nA3\nA4\nA5\nA6\nA7\nA8\nA9\nA10\nA11\nA12"
                        width: scrollRect.width
                    }
                }
            }
        }
    }
}

The issue happens when I run the application in a tablet with a touchscreen.

In Qt5 (tested with 5.15.2), I can scroll the text ScrollView by dragging the finger over the text.

In Qt6 (tested with 6.2.4), I cannot scroll the text ScrollView by dragging the finger over the text. Only if I connect a mouse I can scroll it or interact with the scrollbars. Using the fingers I can only scroll the whole listview. The scrollbar up/down buttons also have no effect if I tap them.

I'm not sure if this has to do with the following quote from the manual:

Note: As of Qt-6.0, ScrollView automatically clips its contents if you don't use a Flickable as a child. If this is not wanted, you can set your own Flickable as a child, and control the clip property on the Flickable explicitly.

But I don't know how to fix it.
