dotnet format does not respect global.json and breaks when preview versions of .NET is installed

I am unable to use dotnet format in my projects because it throws the following error:
```
Unhandled exception: System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types.
Could not load file or assembly 'Microsoft.CodeAnalysis.CSharp, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.
```

This seems to be because it is trying to load assemblies from .NET 6.0.200 preview even though I have the following global.json in my project:
```json
{
"sdk": {
"version": "6.0.100",
"allowPrerelease": false,
"rollForward": "latestFeature"
}
}
```

The following log output illustrates the problem:
```
> dotnet format -v diag --verify-no-changes .\project.sln

The dotnet runtime version is '6.0.1'.
The dotnet CLI version is '6.0.101'.
