In new version of Webbrowser (18.0.65) after setting custom UserAgent - reCaptcha not loaded.
For example, even if we set a default User Agent:
WebView.CustomUserAgent="Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.9 Safari/537.36"

then load this page: http://google.com/recaptcha/api2/demo
and try to click "I'm not a robot" checkbox - nothing happens.

The same problem occured if we trying to set WebView.AcceptLanguage to different value.
For example, WebView.AcceptLanguage = "ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3";

In older versions of Webbrowser (2017) it works fine.
If CustomUserAgent or AcceptLanguage is not set - all works fine too.

This captcha is used on many sites, and it will be good if there is a solution to this problem

Thank you.

In version 18.0.70 problem is solved! Thanx
