QTcpSocket is disconnected once the peer shuts down send/recv operations

When the remote peer uses shutdown any operation on its end, the local QTcpSocket closes the connection (RemoteHostClosedError).

Native socket functions are perfectly fine with this, and do not close the connection.

About the attachment:
There are two QtCreator projects - server and client.
Server listens on localhost:12345, and prints a message once a client disconnects.
Client connects to localhost:12345, and attempts to shut down its write operation, it does not call disconnectFromHost anywhere.
