How session management works is that the application connects to the
QGuiApplication::saveStateRequest() signal. When that signal arrives,
the application either saves its state or calls
QSessionManager::cancel() on the instance passed in the signal. Session
management never works by just trying to close windows without telling
the application that it was triggered by session management. In the
absence of any proper mechanism, one *could* do it that way, but it's a
bad idea because relevant information and actions are not available to
the application that way.
