    Description

      In our application we update the menu bar depending on the view that is currently displayed. Some views can also be detached from the main window and appear in their own instance of a QMainWindow. When detaching, the views actions and menus are also transferred. Of course such a detached view can again be re-attached to the main window.

      On macOS there is some magic that occurs when adding an "Edit" menu to the menu bar: some default edit items are appended (like "Start dictation" and "Emoji & Symbols") to the Edit menu. These new actions trigger eventually crashes when the Edit menu gets transferred to a different QMainWindow.

      In a debug build we see (one of) the following messages right before the crash occurs: 

      Warning: Debug: Menu item "" already in menu "Edit"
Warning: Debug: Menu item "Start Dictation..." already in menu "Edit"
Warning: Debug: Menu item "Emoji && Symbols" already in menu "Edit"
Warning: Debug: Item to remove does not belong to this menu

       A debugger pointed to this problem: 

      2022-10-13 11:19:56.164 a3c[58525:4531717] *** -[QCocoaNSMenuItem isSeparatorItem]: message sent to deallocated instance 0x60000032e980

       The backtrace we get looks as follows: 

      Assert: Caught fatal signal 11 (Segmentation Violation).
