This is a general issue with tabulated-list-mode -- there's no way to
get back to the original order after sorting.
That is, the caller will put the data in `tabulated-list-entries', and
it'll be displayed in that order. When sorting, tabulated-list-mode
will then sort on the data in a column, and that destructively modifies
`tabulated-list-entries'.
So to get back to the original order, we can't rely on re-sorting -- we
really have to know what the original order was, which means that we
have to store that somewhere. I've now done so in Emacs 28 (stashing it
in a hash table instead of making a copy of the list itself, in case
that has had elements removed in the meantime).
It takes up some extra memory, but it's not done until the user issues a
sorting command, so I think it should be OK.
