QNetworkConfigurationManager::updateConfigurations () cannot discover QNetworkConfiguration::Undefined WLANs's networkConfigurations

In the attached small demo, the application output can print all the networkConfigurations by using QList<QNetworkConfiguration> QNetworkConfigurationManager::allConfigurations ( QNetworkConfiguration::StateFlags filter = 0 ) const
but it does not print the WLANs's Configurations which has not been defined or connected.
