When connecting to child session(or a VM), we have CredSSP/Nego/ActivationSequence
instead of Nego/CredSSP/ActivationSequence. Before the patch, we were not applying
flags read in the NegoResponse to the settings and that was leading to FreeRDP
thinking that the remote server was not supporting EXTENDED_CLIENT_DATA_SUPPORTED.
That was later preventing some GCC blocks to be sent, and make the server unhappy
and freeze the connection.
