[Problem/Bug]: [ Broken] Events NewWindowRequested and WindowCloseRequested are not working together

[DotNet-Fan]

What happened?

Webview2 WindowCloseRequested is not firing at all. This is broken.
We subscribe to NewWindowRequested and WindowCloseRequested events.
In the NewWindowRequested handler, we set the new window parent to the same webview2 instance so that it would show in the same webview2 instance.
This is for the Google social login which would be opened by default as a new window popup.

private void CoreWebView2_NewWindowRequested(CoreWebView2 sender, CoreWebView2NewWindowRequestedEventArgs e)
{

e.Handled = true;
if (sender != null)
e.NewWindow = sender;
}

When the google social login popup is closed after login , the WindowCloseRequested event does not fire at all.
This was working earlier.

Importance

Blocking. My app's basic functions are not working due to this issue.

Runtime Channel

Stable release (WebView2 Runtime)

Runtime Version

136.0.3240.92

SDK Version

Microsoft.UI.Xaml.Controls - v 2.8.7

Framework

WinUI2/UWP

Operating System

Windows 11

OS Version

Microsoft Windows [Version 10.0.22631.4317]

Repro steps

In UWP App , add a webview2 control.
Then make sure that Corewebview2 is initialized using EnsureCoreWebView2Async call.
Once initialized in the CoreWebView2Initialized handler subscribe to CoreWebView2.NewWindowRequested and CoreWebView2.WindowCloseRequested event.
In the CoreWebView2.NewWindowRequested handler add the below code

private void CoreWebView2_NewWindowRequested(CoreWebView2 sender, CoreWebView2NewWindowRequestedEventArgs e)
{

e.Handled = true;
if (sender != null)
e.NewWindow = sender;
}

• Navigate to www.x.com or www.pinterest.com and click on Google login.

• This opens the google new window in the same instance of webview2.

• After successful login and close of the popup , the WindowCloseRequested event is not fired .

This was working earlier and the code is broken now.

Hi @DotNet-Fan,

I am confused by this point, mentioned by you in the description:

Regression
No, this never worked

Last working version (if regression)
130.0.2849.68 

Could you please check and share if it was working in 136?

@sivMSFT This is not working in 136. The version that we have integrated is 130 (fixed version) and it worked. Updated description.
