How to set a viewport with QtWebEngine?

[domusmaximus]

I have created a application with a QWebEngineView widget with a width of 500px. However when viewing websites like google.com the website is not recognizing the fact that it is a small windows and still displaying the full site.

Because of this you can only see the top corner of the webpage. I am assuming this is because QWebEngineView is not setting a viewport. This used to be possible in QWebKit, is there any work around for QWebEngine?
