CefSharp 79.1.360 (Winform)：如何在LifeSpanHandler中重新激活弹出窗口

public class CustomLifeSpanHandler : ILifeSpanHandler
{
    public bool DoClose(IWebBrowser chromiumWebBrowser, IBrowser browser)
    {
        // 在此处处理关闭窗口的逻辑
        return false;
    }

    public void OnAfterCreated(IWebBrowser chromiumWebBrowser, IBrowser browser)
    {
        // 在此处处理新窗口创建后的逻辑
    }

    public void OnBeforeClose(IWebBrowser chromiumWebBrowser, IBrowser browser)
    {
        // 在此处处理窗口关闭前的逻辑
    }

    public bool OnBeforePopup(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures, IWindowInfo windowInfo, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
    {
        // 在此处处理弹出窗口的逻辑
        newBrowser = null;
        return false;
    }
}

var settings = new CefSettings();
settings.RegisterScheme(new CefCustomScheme
{
    SchemeName = "custom",
    SchemeHandlerFactory = new CustomSchemeHandlerFactory()
});

Cef.Initialize(settings);

var browser = new ChromiumWebBrowser("custom://localresource/index.html");
browser.LifeSpanHandler = new CustomLifeSpanHandler();
