I build a small browser with cefsharp. When I go with my browser on https://www.kitanetz.de/bayern/86447/schulstr-29.php then I see the following: https://i.stack.imgur.com/FKtUM.png

When I use for example firefox, I see the following: https://i.stack.imgur.com/91GCq.png

Do someone have an idea why this happen?

Thank you and best Regards
