Primary constructor parameter gives incorrect "could be static" warning

[KathleenDollard]

Version Used: Version 17.7.0 Preview 1.0 [33603.545.main]

Steps to Reproduce:

1. Compiler this code:

using System.Collections.Generic; 
using System.Linq;

public class Student(int id, string name, IEnumerable<decimal> grades)
    {
        public Student(int id, string name) : this(id, name, new List<decimal>()) { }
        public int Id => id;
        public string Name { get; set; } = name.Trim();
        public decimal GPA => grades.Any() ? grades.Average() : 4.0m;
    }

2. Check for warnings

Diagnostic Id: CA182

Expected Behavior: Does not offer to change to static.

Actual Behavior: For two of the three primary ctor parameters in the example, an offer is made to change to static. It is not clear why 2 of the 3.

This is blocking hte ability for Roslyn to use primary constructors itself. Can you guys please prioritize this?
