"Delegate invocation can be simplified" is shown on non-delegates

[jnm2]

Version Used: 17.13.0 Preview 2.0

The following code produces "ℹ️ IDE1005 Delegate invocation can be simplified," but this is not delegate invocation. Nothing needs to be shown here, because this refactoring is duplicative of the "Null check can be simplified" that is also offered on the same line.

var expr = new C();
if (expr != null) expr.Invoke();

class C
{
    public void Invoke() { }
}
