However, in order to satisfy the test, some overrides are also added to ReverseOrderSortedMapView, which is used by the SortedMap wrapper keySet, values, and entrySet views. These overrides don't do anything except to call super, so they're arguably dead code. However, they enable all combinations of sequenced map views to be tested, which is valuable.

Maybe not, because this extends the nearby `SynchronizedSortedSet` which has the overridden default methods. Would it still be worth considering overriding those here too?
