✅ `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);
}

Gives

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?
