Looks a bit confusing the number of variables we have to track as we
swap between original and new, then fallback or commit. But I didn't
spot anything obviously wrong in how you did it. I suspect that if we
ever convert over to having domain XML track full backing chain
semantics, we will have a lot to rewrite in this area of code to take
advantage of that, but the future shouldn't hold up incremental progress
in the present. ACK.
