CS1580 fired with a paramater that is generic and nullable (xml doc)

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

I'm using VS2019 16.1.1 (in VS2017 15.9.12 this does not happen)
The app is using .net core 2.2, and the analyzers Microsoft.CodeAnalysis.FxCopAnalyzers 2.9.2
StyleCop.Analyzers 1.1.118

I have method with this definition:

public static bool HasValue<T>(this T? source) where T : struct

and in a xml doc I have this:

/// <summary>
/// Internally uses <see cref="TypeValidations.HasValue{T}(T?) "/>.
/// </summary>

In VS2019 this fires the error:

Error CS1580 Invalid type for parameter T? in XML comment cref attribute: 'TypeValidations.HasValue{T}(T?) '

If I change the documentation to TypeValidations.HasValue{T}(Nullable{T}) now I got an analyzer error (SA1125) telling me that I should use the shorthand notation for nullable types.
