CoreWebView2NewWindowRequestedEventArgs.Handled does not prevent new window

[dimmelsw]

Description
CoreWebView2NewWindowRequestedEventArgs.Handled does not prevent new window.

Version
SDK: 1.0.674-prerelease
Runtime: 86.0.622.48
Framework: WinForm
OS: Win10

Repro Steps
Handle coreWebView2.NewWindowRequested-Event
Set CoreWebView2NewWindowRequestedEventArgs.Handled to true

private void CoreWebView2_NewWindowRequested(object sender, CoreWebView2NewWindowRequestedEventArgs e)
{
	e.Handled = true;
}

I expect WebView2 not to open a new window.
Instead I want to open a custom window.

Additional context
It worked as expected in 0.9.579-prerelease

Thanks for reporting this. I've opened a bug on our end and we'll take a look. Thanks!

I have found this to be an issue as well. e.handled does not work anymore. Also, if I let webview2 handle the popup (e.handled = false), the popup does not size itself to the window.open sizes specified. Also, if I handle the new window (e.handled = True) and open my own window, that works fine, but if I set e.NewWindow to the window I opened and then popup another new window, it opens a 2nd window instead of reusing the one already opened.

Hi Everyone,

This was addressed in the 1.0.664.37 version.

Hi. I went and got Webview2 version 1.0.707-prerelease to test this out. With this version I cannot get the Webview2 to initialize. Keep getting 'Object reference not set to an instance of an object'. I have tried many things, but cannot resolve the issue.

@ronschmidt55 Could you see if you are running into #678?

[ronschmidt55]

Yes, same issue. Version 1.0.721-prerelease fixed the issues. Thanks
