      Description

      Hi,

      The following snippet crashes in Qt6 (but not in Qt 5.15):

      import QtQuick 2.0
      import QtQuick.Window 2.1
      
      Window {
          component TestPopup: Window {
              visibility: Window.Windowed
          }
          TestPopup { color: "blue" }
      }
      

      With the following stack trace:

      gdb --args ./Work/Qt/6.0.1/gcc_64/bin/qml testwindowvis.qml
      ...
      (gdb) bt

      Instead a runtime error should be thrown, ie:

      file:///home/rawoul/testwindowvis.qml:6:9: "Window.visibility" is not available in QtQuick 2.0.
