Can't extract method on case expression in match/case clause.

[CyrusNajmabadi]

 p match (
            case Student s when s.Gpa > 3.5 :
                $"Honor Student { s.Name } ({ s.Gpa })")

Trying to extract out the string literal extracts out the entire match/case expression into a new method.

The match expression is not in scope for the current punch-through.

This issue is verified reproducible in the current prototype:

class Program5
{
    string M(Person p)
    {
        return p switch {
            Student s when s.Gpa > 3.5 => $"Honor Student { s.Name } ({ s.Gpa })",
            _ => throw null
        };
    }
}

class Person
{
}
class Student : Person
{
    public double Gpa;
    public string Name;
}

This works fine now. Closing out:
