    Description

      Freeze all main loop. User can't work with program after opening sites with reCAPTCHA.
      For example this demo https://www.google.com/recaptcha/api2/demo.

      Program:

      #include <iostream>
#include <QApplication>
#include <QtWebKitWidgets/QWebView>

int main(int argc, char** argv) {
  if (argc < 2){
      std::cerr << "no url" << std::endl;
      return 1;
  }
  const char* const url_str = argv[1];
  QApplication app(argc, argv);
  QWebView view;
  view.show();
  view.setUrl(QUrl(url_str));
  return app.exec();
}

      Run with link looks like this:

       

      The program is dead .

       

      Get this on other urls, for example - https://www.dssl.ru/files/trassir/manual/es/setup-local-server.html

      Checked QNetworkReply from finished signal = `"Unknown error"`
      After few minutes program don't respond, see in log
      `qt.network.http2: stream 133 finished with error: "HTTP/2 protocol error"`. But result can be different with other urls.
