QML Menu right-to-left bug

[Imynn]

Hello Everyone! I've encountered an issue, when I try to use Menu from QtQuick.Controls 1.4 and if my application is QApplication that has right-to-left layout. When I try to open a menu it popups in a right place but then moves on its width to the left side. This problem doesn't happen with QGuiApplication. Anyone else encountered this issue? Are there any solutions for this? I'm using Qt 5.12.12. The same issue appears on Qt 5.15.2 as well.
Simple example:

import QtQuick 2.9
import QtQuick.Window 2.3
import QtQuick.Controls 1.4
Window {
    id: root
    width: 640
    height: 480
    visible: true

    Menu {
        id: menu
        MenuItem {
            text: "Hello"
        }
    }

    MouseArea {
        anchors.fill: parent
        onClicked: {
            menu.popup()
        }
    }
}

Thank you for help in advance
