Launching an external or a custom URI scheme in a new window provided by `add_NewWindowRequested` does not work

Description
It is impossible to launch a URI scheme which is registered with the OS (external) or by WebView2's ICoreWebView2CustomSchemeRegistration (custom) and directed to a new window that is provided by add_NewWindowRequested. A new window is opened but nothing happens. The invocation works if the pop-up window is handled by WebView2 itself. It doesn't matter if the scheme is called by window.open or an anchor with target '_blank'.

Repro Steps
This can be reproduced in WebView2APISample. Obviously, an external scheme is needed but WebView2APISample's custom scheme "calculator://" suffices:

1. Launch WebView2APISample.
2. Open a console.
3. Execute window.open("calculator://");. Executing window.location.href = "calculator://"; works as expected.

Start in WebView2APISample and trace the add_NewWindowRequested handling for window.open("calculator://") versus window.location.href. Reproduce the issue with the custom calculator:// scheme, then verify that a URI opened in the supplied new window launches successfully for both custom and external schemes.
