How to popup a new browser window(at the same time, keep communication with parent window)

[GuopinChen]

1. There is a browser window, I hope using "window.open" to popup a new window
2. And I set the MyLifeSpanHandler.OnBeforePopup with code below:

public bool OnBeforePopup(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures, IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
{

    newBrowser = Application.Current.Dispatcher.Invoke(() => 
    {
        ChromiumWebBrowser br = new ChromiumWebBrowser(targetUrl);
        br.LifeSpanHandler = new LifeSpanHandler();
        br.KeyboardHandler = new KeyboardHandler();
        br.JavascriptObjectRepository.Settings.LegacyBindingEnabled = true;
        br.JavascriptObjectRepository.Register(nameof(JsBridge), new JsBridge(), CefSharp.BindingOptions.DefaultBinder);

        br.SetAsPopup();
        return br;
    });
    // use native cefsharp window , to keep communication with parent window 
    return false;
}

3. When I try to call the registered bridgeObj with JsBridge.doSomething() in devtool, the actual c# method has never been called. And the CefSharp always try using the objectId in parent window to call JsBridge.doSomething(), so it can not find the real JsBridge object and execute the method correctlly.

when open url with same host, object Id of JsBridge not matched

when open url with different host , JsBridge is not observed in devTools.

Is there someone facing a similar problem? How can I resolve it. I'm using Cefsharp.Wpf.

This is my demo

one more thing, the parent window is a wpf window

Using LegacyBinding where the objects are specified on the popup directly isn't supported currently. It might be possible, though would require code changes.

Using CefSharp.BindObjectAsync should work
