skip_sid and other arguments are not passed on to socketio.emit

[smackware]

Describe the bug
I notice that skip_sid is ignored (client would receive messages although I explicitly stated them not to, as pet the documentation)
The emit function in init.py explicitly emits that argument and many other possible arguments

To Reproduce
Steps to reproduce the behavior:

1. Set up a server using flask_socketio
2. Create a simple event that emits back a message, with skip_sid=request.sid
3. A client that send that former event, see client receiving the event even though their SID is in skip_sid

Expected behavior
Client who is specified in skip_sid should not get the message

Logs

Additional context
I created a workaround which I believe should also serve as the proper content of the emit function itself:

def emit_(*args, **kwargs):
    if 'namespace' not in kwargs:
        kwargs['namespace'] = flask.request.namespace
    if 'room' not in kwargs:
        kwargs['room'] = flask.request.sid
    socketio.emit(*args, **kwargs)
