MSIX: Container escape
Packaged up Notepad++ using the MSIX Packaging Tool.
The tool fails to detect that the main program can elevate itself. I am guessing it isn't manifested and is code based elevation.
Using the packaged version running in a container, open up a text file from c:\Windows, make a change and try to save the file. Notepad++ will detect that you can't write to that location and via popup offer to elevate so that you can. This elevation creates a new Notepad++ that is elevated and running outside of the container.
