VS debugger variable expansion is broken by nullable ref-returning properties

[kindermannhubert]

Version Used:
VS 18.1.1

Steps to Reproduce:
Set a breakpoint after the following code, run, and when the breakpoint is hit, try to expand c1/c2/c3/c4 variables in Watch/Locals/Autos windows or by hovering over the variable with a cursor. Expansion of c1/c2/c3 works as expected, but c4 cannot be expanded, although C4 and C2 differ only in used type (int? vs int).

class C1
{
    public int A = 1;
}

class C2
{
    public int A = 1;
    public ref int B => ref A;
}

class C3
{
    public int? A = 1;
}

class C4
{
    public int? A = 1;
    public ref int? B => ref A;
}

var c1 = new C1();
var c2 = new C2();
var c3 = new C3();
var c4 = new C4();

Expected Behavior:
All instances c1/c2/c3/c4 can be expanded.

Actual Behavior:
c4 cannot be expanded.
