I think there are already tests to ensure that list.reversed().reversed() returns the original list. See also https://github.com/openjdk/jdk/pull/24990 which adds some tests (but these are mostly about synchronized wrappers and propagation of RandomAccess). But we can assess the need for tests after 24990 is integrated.

As I noted in the bug report ReverseOrderListView.reversed() really does end up returning base, but it does so in a roundabout fashion that could be cleaned up by adding the override as is done here.
