oAuth 2.0 has stopped working since electron (Chromium client)

Hello!

My oAuth 2.0 remains waiting when I choose direct Dropbox account. And only in Electron 1.8.4. The next image belongs to the app I'm developing. App name has been deleted to protect my company data.

I think that the problem is self described in the image. It remains permanently waiting in "Iniciar Sesión" button clicked. Only in electron 1.8.4. In Chrome it works fine.

The problem is that the authentication flow doesn't reach the redirect uri. (If you want more info about concrete app and redirect uri I can give you via private message).

About your questions: 

* Dropbox / SDK library: HTTP (REST API). Version 2: https://www.dropbox.com/developers/documentation/http/overview

* the full text of the error/any unexpected output, or a screenshot/screencast of any broken functionality: in this response it is

* the steps to reproduce the issue, including relevant code snippet(s): 

The problems appears in Windows 8.1 and Mac OSX Sierra.

Electron installed version 1.8.4.

Code snippet to launch the client inside electron window:

var state = '...';
var options = {
    hostname : 'www.dropbox.com',
    pathname : '/oauth2/authorize',
    method : 'GET',
    query : {
        client_id : dropbox.APP_ID,
        response_type : 'code',
        redirect_uri : 'https://.../dropboxauthcallback',
        state : state
    }
};
var route = url.format(options);
route = 'https://'+route;

openInNewTab(route);

var openInNewTab = function(url) {
    var win = window.open(url, '_blank');
    win.focus();

}

Electron has stopped working since some days ago.

Thank you!
