Dana Jansens db87a84b69 Improve tests and clarify design for observe equivalence chains (#7987) ...

Update tests for observe equivalence chains to cover more cases and to
better test the things they meant to. The design is clarified to explain
that in an `interface` the types in an equivalence chain must all be
related to that interface except for one.

This is based on #7484 with some followup changes by me.
