The WebBrowser control in WinForms use a legacy version of IE by default. (IE7)

That is most likely the cause of your issue, to solve it you would have to force the WebBrowser emulation to a higher version, IE11 for example, in the windows registry.

This is a piece of code I use to do so by detecting currently installed IE version and updating it in the registry:

                int BrowserVer, RegVal;

            // get the installed IE version
            using (WebBrowser Wb = new WebBrowser())
                BrowserVer = Wb.Version.Major;

            // set the appropriate IE version
            if (BrowserVer >= 11)
                RegVal = 11001;
            else if (BrowserVer == 10)
                RegVal = 10001;
            else if (BrowserVer == 9)
                RegVal = 9999;
            else if (BrowserVer == 8)
                RegVal = 8888;
            else
                RegVal = 7000;

            // set the actual key
            RegistryKey Key = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
            Key.SetValue(System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe", RegVal, RegistryValueKind.DWord);
            Key.Close();

Simply paste the code at the beggining of your application. Furthermore, refer to this answer for extra details.
