Ignore does not appear to work

[PhilipDaniels]

Given a model

public class Car
    {
        public Car()
        {
            Bag = new Dictionary<string, object>();
        }

        public IDictionary<string, object> Bag { get; }
    }

I want to ignore all changes in the Bag. I expected this to work

        [Fact]
        public void Ignore_ShouldIgnoreCollections()
        {
            var original = new Car();
            var current = new Car();

            current.Bag["foo"] = "bar";

            var configuration = new Configuration();
            configuration.Configure(config => config
                .Entity<Car>(e =>
                {
                    e.Property(p => p.Bag).Ignore();
                    //e.Collection(p => p.Bag).Ignore();
                }));

            var comparer = new EntityComparer(configuration);

            var changes = comparer.Compare(original, current);
            changes.Count.Should().Be(0);
        }

But I get 1 diff. The commented out Ignore() does not help either.

I believe the error may be in EntityComparer.CompareObject. Changing the loop as below fixes the issue, but I don't know if there are other ramifications.

            foreach (var memberMapping in classMapping.Members)
            {
                if (memberMapping.Ignored)
                    continue;
