Completion Items don't work with Inner Classes

There are many examples of this, but this is the simplest snippet that illustrates completion lists not working with inner classes:

using System;
using System.Collections.Generic;
using System.Linq;

namespace DotNetLanguagesAddon {
	public class OuterClass {
		public class InnerClass { public int InnerValue { get; set; } }
		
		public InnerClass InnerClass { get; set; }
	}
	
	public class CSharpLanguage {
		public void DemoTest() {
			var outer = new OuterClass();
			outer.InnerClass./* No Completion Items! */
		}
	}	
}
