[Problem/Bug]: Cannot suppress (Camera) permission prompt

What happened?

Using WebView2, it appears like certain websites can prompt for permissions, like Camera permissions. I need to deny those permissions on behalf of the users - no permission prompt should be shown.
The CoreWebView2.PermissionRequested event handler is not called.

Importance

Moderate. My app's user experience is affected, but still usable.

{
    c.CoreWebView2.PermissionRequested += (sender, args) =>
    {
        args.Handled = true;
        args.State = CoreWebView2PermissionState.Deny;
    };
};
webView.Source = new Uri("https://webcamtests.com/");

Last working version (if regression)

No response

Start with the CoreWebView2Initialized and CoreWebView2.PermissionRequested handlers in the repro, then compare the behavior with the corresponding Edge version. Determine why the camera permission event is not raised and whether the requested denial behavior can be achieved; done means the cause and a verified resolution are documented or implemented.
