我正在从我的网站加载cefsharp中的网页，该网页仅在iframe中保存了fb之类的插件
<!DOCTYPE html>
<html>
<head>
<title>Like our Facebook page</title>
</head>
<body>
<iframe src="https://www.facebook.com/plugins/like.php?href=https%3A%2F%2Fwww.facebook.com%2Fmypage%2F&width=450&layout=standard&action=like&size=small&show_faces=true&share=true&height=80&appId=realappid" width="450" height="80" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true"></iframe>
</body>
</html>
它可以很好地加载页面，但是当我单击“赞”按钮时，它会显示屏幕外的Facebook登录对话框，即使我从任务栏中单击它也无法将其显示在前面。
public ChromiumWebBrowser socialBrowser;
//LOAD FB LIKE PAGE
socialBrowser = new ChromiumWebBrowser("http://mywebsite.com/fb.html")
{
RequestHandler = new BrowserRequestHandler()
};
fb iframe本身会出现问题吗？ 这是附加到浏览器实例的BrowserRequestHandler类。
