Add Missing Constructor - A protected constructor is generated for a sealed class, which should be public

Hi,

1.Standing in Attribute - add missing constrctor generates protected constrctor while the calss seal
   [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple= true )]
    public sealed class CodeReviewAttribute : Attribute
    {

        public CodeReviewAttribute(string name, DateTime date, bool isApproved)
        {
            Name = name;
            Date = date;
            IsApproved = isApproved;
                    
        }
           
     
         
        public string Name { get; private set; }
        public DateTime Date { get; private set; }
        public bool IsApproved { get; private set; }
    }

2.Current results:
   [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple= true )]
    public sealed class CodeReviewAttribute : Attribute
    {

        public CodeReviewAttribute(string name, DateTime date, bool isApproved)
        {
            Name = name;
            Date = date;
            IsApproved = isApproved;
                    
        }
        protected CodeReviewAttribute()
        {
            
        }
         
            
     
         
        public string Name { get; private set; }
        public DateTime Date { get; private set; }
        public bool IsApproved { get; private set; }
    }

3.Expected:
   [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple= true )]
    public sealed class CodeReviewAttribute : Attribute
    {

        public CodeReviewAttribute(string name, DateTime date, bool isApproved)
        {
            Name = name;
            Date = date;
            IsApproved = isApproved;
                    
        }
        public CodeReviewAttribute()
        {
            
        }
         
             
     
         
        public string Name { get; private set; }
        public DateTime Date { get; private set; }
        public bool IsApproved { get; private set; }
    }

Thanks,
