c#Cefsharp SendMouseClickEvent点击网页输入框无光标，无法输入？

cefSharp winform想能够自动登录 雷蛇网站. https://gold.razer.com/. 在登录框的时候，SendMouseClickEvent能点中 用户名 密码输入框,可是没有光标， 也就无法进行下一步的输入。请问什么原因？

 private void ClickElement(string selector)
        {
            var sSel = $"$('{selector}').offset();";
            Task<CefSharp.JavascriptResponse> t = browser.EvaluateScriptAsync(sSel);
            t.Wait();
            if (t.Result.Result != null)
            {
                var expandoDic = t.Result.Result as IDictionary<string, object>;
                if ((null != expandoDic) && expandoDic.ContainsKey("left") && expandoDic.ContainsKey("top"))
                {
                    var left = Convert.ToInt32(expandoDic["left"]) + 5;
                    var top = Convert.ToInt32(expandoDic["top"]) + 5;                   


                    browser.GetBrowser().GetHost().SendMouseClickEvent(left, top, MouseButtonType.Left, false, 1, CefEventFlags.LeftMouseButton);
                    Thread.Sleep(120);
                    browser.GetBrowser().GetHost().SendMouseClickEvent(left, top, MouseButtonType.Left, true, 1, CefEventFlags.LeftMouseButton);

                }
            }
        }

        

        private void button1_Click(object sender, EventArgs e)
        {
            //
            browser.ExecuteScriptAsync(File.ReadAllText(@"jquery.min.js"));
            ClickElement("#input-login-email");
           
        }

已解决，更新CEF 解决

不太懂，还需要设置焦点？
我看参数都用的是CefEventFlags.None
