S1128 raised when namespace is referenced by type used in comment

Having the following class:

namespace TestNameSpace
{
  using System.Collections.Generic;

  /// <seealso cref="List{T}" />
  public class Test
  {
  }
}

The sonarqube server (version 9.4.0) reports the issue “S1128 Remove this unnecessary ‘using’” for the using statement even the namespace is used, but “only” in the comment.

I think this is a false-positive.

Hey there.

Thanks for the report. We are already tracking this false-positive here! Fix S1128 FP: documentation tags with dotnet build command · Issue #3633 · SonarSource/sonar-dotnet · GitHub

Yes, it looks simlar.
Unfortunately it is open since more than one year…

You could not reproduce it?
I also tried to make it reproducible in sonar-dotnet. But I failed (too).

Any idea?
