Access/Mnemonic key in Qt Control does not work for top level menu

 menuBar: MenuBar {
        Menu {
            title: "&File"
            MenuItem { action: fileOpenAction }
            MenuItem { text: "Qui&t"; onTriggered: Qt.quit() }
        }

In above code snippet on windows hitting Alt+F does not pulls down the File menu but hitting Alt+t quits the application.
