Non-modal Drawer blocks shortcuts

Hello everyone,

I am in Qt 5.15.1, I stumbled on an issue while using the Drawer item. I followed the example "Qt Quick Controls - Side Panel" . The idea is to create a non-modal drawer usable as a fixed side dock when the the width of the window is sufficient.

Yet, I found out by trials and errors that Shortcut items, "shortcut" properties in Action andr more worrisome (for me) the "Alt+...." shortcuts in the ApplicationWindow.menuBar are unusable. If these are created as children of Drawer, no problem. If the drawer is not "visible", all shortcuts are working. The moment the non-modal drawer is "visible", the parent/ancestors' shortcuts are lost.

I found a little workaround in adding context: Qt.ApplicationShortcut to Shortcut and coupling each Action with a Shortcut to use this property. Yet, the menuBar is still out of reach of shortcuts.

I find strange that a non-modal Drawer blocks all its ancestors shortcuts. I know it's inheriting Popup behavior, but it makes using the Side Panel idea difficult.

Is it a bug ?  Any idea for a workaround ? Do I need to couple all shortcuts from Action or menus with the snippet below :

Shortcut { 
sequence: KeySequence.Save 
context: Qt.ApplicationShortcut 
onActivated: saveAction.trigger() 
} 

Here is a working example, switch the visible property of the drawer to see the difference. Type Ctrl+A, Ctrl+B and Alt+F and read the result.

import QtQuick.Window 2.15
import QtQuick 2.15
import QtQml 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    id: base
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")  
 
    Drawer {
        id: leftDrawer
        parent: base
        visible: true // switch to false 
        width: 200
        height: base.height
        modal: false
        interactive: false
        edge: Qt.LeftEdge 
      
        Rectangle{
            color: "red"
        }        
        
        Action {
           shortcut: "Ctrl+B"
           onTriggered: {
           console.log("Ctrl+B")
            }
        }
    }
            
    Action {
        shortcut: "Ctrl+A"
        onTriggered: {
        console.log("Ctrl+A")   
          }
    }    

menuBar: MenuBar{       
             Menu {
                id: fileMenu
                title: qsTr("&File")

                MenuItem{
                    text: "Save"    
                }
            }
        }
}

Thank you  !

Edit: Still not working under Qt 6.7, with the imports as :

import QtQuick.Window
import QtQuick
import QtQml
import QtQuick.Controls
