Can you add a tests for moving Class1 and Class2 with this setup? Assuming this is valid with filescoped namespaces

namespace N1;

class Class1 
{
    Nested.Class2 C2 { get; }
}

namespace Nested
{
    class Class2 { }
}

that's not valid. it's illegal to mix/match a file-scoped namespace with any other sort of namespace (including another file scoped namespace).

{
var code =
@"namespace N1;

[||]class Class1 { }
class Class2 { }
";

var codeAfterMove =
@"namespace N1;
class Class2 { }
";

var expectedDocumentName = "Class1.cs";

var destinationDocumentText =
@"namespace N1;

class Class1 { }
";
