Winget isn't working with APPX type packages

Brief description of your issue

Winget isn't working to download APPX packages. For example, the game Flappy Bird can be found in the official MS store website at https://www.microsoft.com/en-us/p/flappy-bird/9wzdncrfjccc but Winget can't find it being present on the MS store when I use the powershell command "winget search 'flappy bird' ". I know it should find it, but it doesn't.

Steps to reproduce

Go to powershell and type in the command "winget search 'flappy bird' "

Expected behavior

It should display the metadata for this app, including the FullPackageName (which is required for the next step of downloading and installing the software via another powershell command).

Actual behavior

It's displaying the error message "No package found matching input criteria.".

Environment

Windows Package Manager v1.6.3482
Windows: Windows.Desktop v10.0.22621.3007
Package: Microsoft.DesktopAppInstaller v1.21.3482.0

Reproduce the issue in PowerShell with winget search 'flappy bird' using the listed Windows Package Manager and Windows versions. Start by tracing how search handles Microsoft Store APPX packages and metadata, then verify that the result includes the app and its FullPackageName without the “No package found” error.
