Doesn't actually install portable executables from zip packages from local manifest

winget install

Brief description of your issue

When testing my manifest on both my dev machine and in Windows Sandbox (with and without your Sandbox script), I found that installing a zip InstallerType with a portable NestedInstallerType and all the right fields - it validates successfully - doesn't actually install the EXE. I also tried on Hugo.Hugo in Windows Sandbox and, though it also succeeded, didn't actually put anything in the package directory that winget --info shows, nor was the command available even after restarting my terminal.

I even tried with the --scope user parameter based on another bug I saw but didn't change anything.

Winget downloads the package, verifies it, and even seems to process it given the timing, but then nothing is in $env:LOCALAPPDATA\Microsoft\Winget\Packages or ...\Links.

Steps to reproduce

1. Clone the winget-pkgs repo (I did a sparse-checkout of { / , !/manifests/, /manifests/h/HUGO } for speed/disk space).
2. Run: .\Tools\SandboxTest.ps1 .\manifests\h\Hugo\Hugo\0.105.0\
3. After install completes, check the User and Machine scope package directories.

Expected behavior

hugo.exe is installed (or, in my attempts to validate my own manifest, akv.exe)

Actual behavior

No files are actually installed.
