Start by locating the sample screen that uses LazyColumn and reproduce the navigation sequence described in the issue. Trace focus restoration when returning from the detail view, using the linked issue tracker report for additional context. Done means the selected nth item, rather than the n-1 item, is focused after navigating back.
