Selection deltas are computed against the `selectedRows` prop instead of stale internal state, so a selection set from outside survives the next checkbox click and `onSelectedRowsChange` emits the correct set. → [Row selection](/docs/selection) ([#1374](https://github.com/jbetancur/react-data-table-component/issues/1374))
