Ignoring Dictionary properties are not working

I have two classes:

    public class Student : EntityBase
    {
        public Guid Id { get; set; }
        public string Name { get; set; }
        public int Score { get; set; }
    }

    public abstract class EntityBase
    {
        public Dictionary<string, object> Test { get; set; }
        public Dictionary<string, object> Test2 { get; set; }
    }

My configuartion:

  static IEdmModel GetEdmModel()
        {
            var odataBuilder = new ODataConventionModelBuilder();
            odataBuilder.EntitySet<Student>("Student");
            var entity = odataBuilder.EntityType<Student>();
            entity.DerivesFrom<EntityBase>();
            entity.Ignore(s => s.Test);
            entity.Ignore(s => s.Test2);

            var baseEntity = odataBuilder.EntityType<EntityBase>();
            baseEntity.Abstract();
            baseEntity.Ignore(s => s.Test);
            baseEntity.Ignore(s => s.Test2);

            return odataBuilder.GetEdmModel();
        }

I am getting error on https://localhost:44383/odata/Student

There should not be this error because I ignored dictionaries

Start at StructuralTypeConfiguration.AddDynamicPropertyDictionary and follow ODataConventionModelBuilder.MapStructuralType and MapTypes while reproducing the Student model and GetEdmModel call. Done means the supplied ignored Test and Test2 dictionaries no longer produce the multiple dynamic property container exception when requesting /odata/Student.
