MessageDialog written in QML are not shown correctly on the Mac (although correct on Linux and Windows).

The bug is also referred in https://forum.qt.io/topic/93370/qml-messagedialog-on-macos-osx

The given workaround is no solution.

A simple example:

MenuItem { 
text: qsTr("About"); 
onTriggered: aboutMessage.open() 
}
 
MessageDialog {
id: aboutMessage 
title: "Licences used" 
text: { "LGPL & BSD" }
}

Output attached - the MessageDialog is "attached to the top", no title and cannot be moved.
