OnBeforePopup creates and sizes window even if one is supplied in newBrowser

[aimcosoftware]

Trying to use onBeforePopup() to create and size a ChromiumWebBrowser as a tab.
Returning the created browser in newBrowser is ignored, a new window is created anyway.

The only way to do that seems to be to create and navigate my own browser, and cancel the default.
This means window.open() doesn't have a reference to the created window.

Anything that can be done to change this behaviour?

Are you using WinForms or WPF? What does your code look like?

If you are using WinForms you can use ChromiumHostControl as per #3529 (comment) This isn't quite as advanced as using ChromiumWebBrowser, it is better tested and more examples.

I'm not add a specific LoadHandler, just using the FrameLoadxxxx events in ChromiumWebBrowser.

I can now confirm the problem is actually in CefSharp

Ah OK, thanks for your time on this. I'm still a bit confused by the default popup events going to the opener, I need to look closer at that.

PR #4443 should resolve this, I've marked it as draft as it will still need some testing.

Great thanks, will give it a try when it's released.

@amaitland Thanks, can confirm that DevTools opens as expected, but there are still other issues related to events being raised on the wrong browser. I'll start a new discussion for that.
