Fixes a bug when undoing dismissal of a SelectionMorph. In the past, this only restored the SelectionMorph itself but not its items.
Please note this solution is not optimal because it abuses #intoWorld:. However, I don't see any unwanted side effects at the moment ... Maybe we would like to introduce an extra hook for this in #reintroduceIntoWorld:?
