In what cases MAUI FilePicker will not return full file path

[rieznikov-firstis]

I want implement File picker in MAUI application according to this article.

https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/storage/file-picker?view=net-maui-8.0&tabs=macios

In our case, we will need to know path to file. But as tip mentioned,

The FullPath property doesn't always return the physical path to the file. To get the file, use the OpenReadAsync method

As I tested, it always returns absolute path to file in macOS. But I want to know in what cases it will not return absolute file path ?
