This seems fine as a fix, though ideally, it would be good to know what’s
causing this so it’s easier to figure out what’s going wrong; my assumption is
that we do something to the pack that causes `IsExpanded` to be true here but
which wouldn’t have been true at the time `FixedNumExpansions` was (not) set.
