We are using Angular Universal to render our Angular 5 app. HTML5 is properly rendered by the NodeJS server, but Google does not render the page visually even if it sees the HTML5.
This is how Google sees the page
This is the code Google sees
So, even if it sees the proper code, it does not render it visually correctly.
Is this harmful for SEO?
Maybe it is caused by a component such as https://material.angular.io/components/tabs/overview, so Google does not render its own library?
