roslyn: The default parameter value for struct and record struct is ignored when a new instance is created

Creating a new structure value via new() automatically and unconditionally replaced by using default() without taking into account the presence or absence of a default value for the parameter

There is no warning about the issue, and the syntax itself is quite acceptable.

There is no such issue for class because there is no such transformation there.

Version Used: .NET 8 RTM SDK

Steps to Reproduce:

using System;

RStruct rStruct = new();
RStructMulti rStructMulti = new(2);
S s = new();
R r = new();

Console.WriteLine($"{rStruct.A}, {rStructMulti.A}, {s.A}, {r.A}");

record struct RStruct(int A = 42);
record struct RStructMulti(int B = 4242, int A = 42);

struct S {
    public S(int a = 42) => A = a;

    public int A { get; }
}

record R(int A = 42);

Expected Behavior:

42, 42, 42, 42

Actual Behavior:

0, 42, 0, 42

RStruct rStruct = default(RStruct);
RStructMulti rStructMulti = new RStructMulti(2);
S s = default(S);
R r = new R(42);
