Socketio established connection domain name path exception

[passingtraveller01]

Client Connection Information：
`var socket = io('ws://abc.com/customRequestPath', {

            query: {
                'clientUserCode': 'my-value'
            },
            reconnection: true,
            reconnectionDelay: 1000,
            reconnectionDelayMax: 5000,
            reconnectionAttempts: 50,
            transports: ['websocket']
        });`

The path for the browser to establish a socket link:

The browser establishes the socket link path is ws://abc.com/socket.io/，And the request path I expect should be ws://abc.com/customRequestPath/socket.io/。

Is this a bug?
