Details

update_focus_data() swaps the widget's geometry and rebuilds it, which returns the map to its idle (unfocused) view – a data swap is treated as a fresh dataset. To keep the user focused on a feature across the swap, pass a state and restore_selection = TRUE through ...; these flow to focus_map() and the new feature is re-focused on load:

update_focus_data(proxy, new_sf, id_col = "GEOID",
                  state = state, restore_selection = TRUE)
