✅ `with` expression does not work with `ValueTuple`

This code:

Foo foo = new();
Foo foo1 = foo with { Bar.Item1 = 1 };

record Foo
{
    public (int, int) Bar = (0, 0);
}

Foo foo = new();
Foo foo1 = foo with { Bar.Item1 = 1 };

record Foo
{
    public (int, int) Bar = (0, 0);
}

Foo foo = new();
Foo foo1 = foo with { Bar.Item1 = 1 };

record Foo
{
    public (int, int) Bar = (0, 0);
}

Foo foo = new();
Foo foo1 = foo with { Bar.Item1 = 1 };

record Foo
{
    public (int, int) Bar = (0, 0);
}

Gives

The name 'Bar' does not exist in the current context

The name 'Bar' does not exist in the current context

The name 'Bar' does not exist in the current context

The name 'Bar' does not exist in the current context on the second line? Why is this?
