Thanks for sharing the video.

It looks like it does work at one point in cefclient (around 2:15 in the video). How is that different from the times that it doesn't work? What does the DevTools console show when it's not working?

In your example the Twitter website is failing to load with the following error:

Uncaught ReferenceError: Notification is undefined.

CEF does not implement the Notification API. This is a bug in Twitter -- they should be checking for its existence before trying to use it.

and why work in chromium ?
this another error on first page witouth login:
Refused to load the image 'https://www.google.it/ads/ga-audiences?v=1&aip=1&t=sr&_r=4&tid=UA-30775-6&cid=1338104929.1468861817&jid=907248013&_v=j44&z=2133516010&ipr=y' because it violates the following Content Security Policy directive: "img-src https://graph.facebook.com https://*.giphy.com https://twitter.com https://*.twimg.com data: https://fbcdn-profile-a.akamaihd.net https://www.facebook.com https://ton.twitter.com https://*.fbcdn.net https://syndication.twitter.com https://media.riffsy.com https://www.google.com https://stats.g.doubleclick.net https://*.tiles.mapbox.com https://www.google-analytics.com blob: 'self'".

You could mock the Notification API by injecting javascript in CefLoadHandler::OnLoadingStateChange.
