[Bug/Feature Request]: ms-windows-store URI schemas not being honored when within a <a> tag in a UWP WebView App on Xbox

[spetrey]

What happened?

I tried clicking on a <a href="ms-windows-store://...">Example</a> deeplink from within a WebView2 UWP App.

Actual: It launches the Xbox App Store

Expected: ms-windows-store://review/?ProductId=9WZDNCRFHVJL would open a Rate and Review Dialog on Xbox

It appears that Windows.System.Launcher.LaunchUriAsync will work if I want to programmatically launch a deeplink from within the C# wrapper. Example from the documentation:

bool result = await Windows.System.Launcher.LaunchUriAsync(new Uri("ms-windows-store://navigatetopage/?Id=Gaming"));

Importance

Moderate. My app's user experience is affected, but still usable. Would be nice to have ms-windows-store:// deeplink working from within the Webview!
