When results resolve for any of the five different types of related
changes, an observer is called which updates the hidden attribute of the
entire related changes UI. Over time, the type of value resolved for two
of these types of related changes evolved, but this code didn't evolve
with them. This resulted in a bug where in certain cases the related
changes section would not appear when it should.
