Issues when files are not part of a subfolder

I'm trying to apply a style fix to some of the projects on dotnet/sdk.

I've tried a bunch of things and none seem to work.

In essence, there is a solution filter at src/RazorSdk/Razor.slnf which contains a set of projects:
* some of them are under src/RazorSdk
* some others are under src/Test
* somne others are under src/BlazorWasmSdk
* I have an editor config where I marked IDE0073 as an error

When I run the following command, I get dotnet-format to apply the fixes correctly
```powershell
Get-ChildItem -File -Recurse -Filter *.cs | Resolve-Path -Relative | dotnet-format -s error --diagnostics IDE0073 .\Razor.slnf --include -
```

However when I try to do the same with files outside of the src/RazorSdk folder no fix is applied no matter what I try. Here are some things I've tried:

#### Passing relative paths from the current folder
```powershell
Get-ChildItem ..\BlazorWasmSdk\ -File -Recurse -Filter *.cs | Resolve-Path -Relative | dotnet-format -s error --diagnostics IDE0073 .\Razor.slnf --include -
```

#### Passing full paths from the current folder
```powershell
Get-ChildItem ..\BlazorWasmSdk\ -File -Recurse -Filter *.cs | Resolve-Path | dotnet-format -s error --diagnostics IDE0073 .\Razor.slnf --include -
```

#### Invoking from the root of the repo
```powershell
Get-ChildItem src\BlazorWasmSdk\ -File -Recurse -Filter *.cs | Resolve-Path | dotnet-format -s error --diagnostics IDE0073 .\src\RazorSdk\Razor.slnf --include -
```

It's not clear to me if I'm doing something wrong, however I would expect paths relative to the sln folder, or absolute paths to the file to work.
