System Tray menu doesn't disappear after clicking outside of it

1. Here is an official page with samples https://doc-snapshots.qt.io/qt5-5.9/qml-qt-labs-platform-systemtrayicon.html 
2. I take this code for testing:

   SystemTrayIcon {
       visible: true
       iconSource: "qrc:/images/tray-icon.png"
   
       menu: Menu {
           MenuItem {
               text: qsTr("Quit")
               onTriggered: Qt.quit()
           }
       }
   } 
   

    

3. Build and run appliation
4. Click on system tray icon (tray menu should be shown)
5. Click outside the system tray menu

Expected result: system tray menu for my application closed automatically

Actual result: system tray menu still visible until one of the items from it will be clicked or system tray icon will be clicked again. 

P.S.: it works on macOS (see attached video)
