current
Version: Version number and/or git branch

Platform(s): Does the problem occur on Windows, Android...?

Describe the bug
Having an empty class on an interface which should be serialized removes all other types from suggestions

To Reproduce
Steps to reproduce the behavior:

1. create an empty interface
2. create 2 classes standard implementing the interface with a body so you have 2 classes with a { } body
3. make a class having it as public property and check in editor that the types are there
4. make one of the classe an empty class like [DataContract] public class Bob : IStuff;
5. reload in editor => drop down only suggests none now

Expected behavior
it should work the same as an empty class with body
