REG 5.9.3->5.94: Components in QQuickWidget does not receive some events from touch

Steps to reproduce:

Take the example quick/quickwidgets/quickwidget as base.
In rotatingsquare.qml, add import QtQuick.Controls 2.1 to the top, then the following inside the root Rectangle:

    Button {
        text: "Button"
        width: root.width / 2
        height: root.width / 3
        onClicked: {
            console.log("Button is pressed")
        }
    }

Run program, click on the button with touchscreen and with mouse

Expected: "Button is pressed" will be printed on stdout for both

Actual: "Button is pressed" is printed only for mouse click, but not on touch click

You can also try a SwipeView. Swiping with touchscreen will fail to swipe pages.

This is a regression in 5.9.4. The same works on 5.9.3.

I suspect it could be a result of the fix to QTBUG-64241, but I may be completely wrong.
