Mouse scroll events stop working with `-platform windows:reverse`

The option `-platform windows:reverse` was introduced to support RTL window title bars (see https://codereview.qt-project.org/c/qt/qtbase/+/42521 ). However, using it causes the Qt GUI to stop responding to the mouse scroll wheel.

Code

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    width: 400
    height: 200
    visible: true
    title: "مرحبا بالعالم"

    LayoutMirroring.enabled: true
    LayoutMirroring.childrenInherit: true

    ComboBox {
        width: parent.width
        model: ["مرحبًا","عالم","مرحبا بالعالم", "aaa", "bbb", "ccc", "ddd", "eee", "fff", "ggg"]
    }
}

Steps to reproduce

1. Add qApp->setLayoutDirection(Qt::LayoutDirection::RightToLeft); to main() and then run the QML code above
2. Click on the combobox and use the mouse wheel to scroll the drop-down menu
3. Close and relaunch the app with the console arguments -platform windows:reverse and repeat the test

Outcomes

• Without -platform windows:reverse the scroll wheel works
• With -platform windows:reverse the scroll wheel does not work
