pacScript config for session.setProxy() method doesn't work in electron v3.0.0-beta.3

[dhammikamare]

• Electron version: v3.0.0-beta.3
• Operating system: Windows 10 Enterprise 10.0.15063 (x64)
• Last known working Electron version: v1.4.16

Expected Behavior
Electron app should either detect Use automatic configuration script mentioned in the Internet Options > Connection > LAN Settings > Automatic Configuration
OR
by passing the pacScript to the .setProxy() method of session object.
https://electronjs.org/docs/api/session#sessetproxyconfig-callback

// in main.js
var electron = require('electron');
var path = require('path');
var BrowserWindow = electron.BrowserWindow;

mainWindow = new BrowserWindow({
    webPreferences: {webSecurity: false},
    width: 1024,
    height: 728,
    kiosk: true,
    backgroundColor: "#000000",
    show: false,
    acceptFirstMouse: true
  }); 

mainWindow.webContents.session.setProxy({pacScript:"http://proxy.xyz.com:9001/production.pac"}, 
    function() {
          mainWindow.loadURL(`file://${path.join(__dirname, "/dist/app.html")}`);
});

Actual behavior
Electron app does not detect proxy settings.

To Reproduce
Setup proxy using a pac script

Additional Information
It does identify the proxy when we pass proxyRules to the ses.setProxy(config, callback)

{proxyRules: "proxy.xyz.com:3128", proxyBypassRules: "localhost"}

OR
when we use Internet Options > Connection > LAN Settings > Proxy Server setting on the windows
