Fixes a styling issue in the Workspace that missstyled class variables from Object as invalid (that is DependentsFields). This is a bug because you can access DependentsFields indeed.

There is a subtle but important difference between the classOrMetaclass nil and the classOrMetaclass Object: The former does not respect any state for styling, but the latter respects class variables from Object (as well as, hypothetically, ProtoObject).

Please note that it would be even more accurate to specify nil class instead of Object here, but I don't know whether we really want to emphasize the nuances of UndefinedObject. It feels rather like an implementation detail for me, at least in this context. (Just imagine UndefinedObject had a UniqueInstance class variable - would we really to access it from any Workspace?) Open for opinions.
