Cookies read/write not working in WebView on WinUI

Description

Reading or writing Cookies (see docs) are not working on WinUI. I think this is because the WebViewRenderer uses the “old” HttpBaseProtocolFilter approach to read/write cookies to the underlying WebView2 control, which does not work. The new approach should be used: https://github.com/MicrosoftEdge/WebView2Feedback/blob/master/specs/CookieManagement.md

Steps to Reproduce

See https://github.com/dotnet/maui/blob/main/src/Compatibility/Core/src/Windows/WebViewRenderer.cs#L255

Affected platforms

Affected platform versions

Did you find any workaround?

I’m using a custom HybridWebView where I (partially) implemented the new solution. See https://github.com/devsmadeofsteel/Plugin.HybridWebView/pull/17

I see that we merged a PR that uses the CookieManager: https://github.com/dotnet/maui/blob/main/src/Core/src/Handlers/WebView/WebViewHandler.Windows.cs#L169

Could someone confirm that this is still an issue with the latest release (6.0.400, released yesterday at the time of writing)

I can confirm this issue is still present.
