By default, both the PermissionRequested event handlers on the
CoreWebView2Frame and the CoreWebView2 will be invoked, with the
CoreWebView2Frame event handlers invoked first. The host may
set this flag to TRUE within the CoreWebView2Frame event handlers

If a deferral is taken on the event args, then you must synchronously
set Handled to TRUE prior to taking your deferral to prevent the
CoreWebView2s event handlers from being invoked.
