"relaxed" property of Request socket is not working as expected

[vm7686]

Describe the bug
The request-reply state is not reset when this flag is set to true.

Reproducing
The code snippet is as follows:

 const zmq = require('zeromq');
 constructor(){
    this.socket = zmq.socket("req",{relaxed: true, correlate:true});	
    this.address = PORT;
    this.init();   	
}

init(){
    var client = this;
    client.socket.connect(client.address);
     console.log('Client connected to',client.address);
  }   

sendMessage(message){
    var client = this;

    return new Promise ((resolve, reject) => {
           
	var ret = client.socket.send(message);
	console.log(ret);		

    client.socket.on('message', (msg) => {	
    console.log('got reply', msg.toString());
    client.socket.removeAllListeners('message');
    resolve(msg);
    });

    client.socket.on('error', (err) => {		               
    reject(err);
    });       

  });//promise

}

Expected behavior
This is the socket.send() event output for a new request when the previous request's response is received

EventEmitter {
_events: [Object: null prototype] {},
_eventsCount: 0,
_maxListeners: undefined,
type: 'req',
_zmq: {
pending: false,
state: 0,
onReadReady: [Function],
onSendReady: [Function]
},
_paused: false,
_isFlushingReads: false,
_isFlushingWrites: false,
_outgoing: BatchList {
firstBatch: null,
lastBatch: OutBatch { content: [Array], cbs: [], isClosed: true, next: null },
length: 0
},
relaxed: true,
correlate: true,
[Symbol(kCapture)]: false
}

},
relaxed: true,
correlate: true,
[Symbol(kCapture)]: false
}
