Fix mutation of commit listing in place

The commit listing on each patch revision started to be flaky when using
browser navigation. It seems like the `Array.sort()` call started to
reverse the order of the commit listing back to HEAD on top which isn't
what we wanted.
`Array.toReversed()` returns a fresh copy of the reversed array which is
less error prone.
