One reopen of a closed file is that file's pane in every jumplist entry

A Back that reopened a file updated only the entry it stepped onto; another entry for the same file stayed closed, and stepping onto it re-looked the file, found it already active and returned without moving, so Forward (or Back) did nothing.
