WinAppSDK app that runs as administrator cause Publisher to be unknown.

Describe the bug

My app is available in Microsoft Store, and the app requires to be run as administrator, the apps runs fine, but when you run it Windows says the publisher is unknown. Which would scare people away, which I can totally understand.

But in the Windows app settings of my app, you can see the publisher is known. It's same as on Microsoft Store.

Isn't this a bug? Windows does know who the publisher of the app is, but when you run it as administrator "it temporarily forgets".

Steps to reproduce the bug

Force Windows App SDK to run in adminstrator.

With these capabilities enabled:

  <Capabilities>
    <rescap:Capability Name="runFullTrust" />
    <rescap:Capability Name="allowElevation" />
  </Capabilities>

And in app.manifest:

  <trustInfo
    xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges
        xmlns="urn:schemas-microsoft-com:asm.v3">
        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>

Expected behavior

I expect app in administrator mode to have publisher from the Microsoft Store.

Additional context

No response

Start by reproducing the packaged MSIX app on Windows 11 21H2 with the listed runFullTrust and allowElevation capabilities and the requireAdministrator setting in app.manifest. Compare the publisher shown in Windows app settings with the administrator launch warning, then determine whether the behavior belongs to Windows or Windows App SDK. Done means identifying a reproducible SDK issue or documenting the platform limitation and next step.
