QtQuickControls2 added an 'opened' prop to Popup in 5.10 (import 2.3) marked REVISION 3 FINAL.

This should not have affected code using older imports in my opinion, but FINAL appears to trump REVISION, meaning that code that had:

    property bool opened

... in a Drawer or Popup etc with the older import version now breaks with the message:

    Cannot override FINAL property

I think that REVISION needs to be checked before FINAL in this case.

Testcase:

import QtQuick.Controls 2.2

Drawer {
    property bool opened: position > 0.0 /* don't be closed until we are fully closed */
}
