Chart behaves identical whether it's dumb (no state) or whether it has state

The docs state that: This is a "dumb" component that doesn't merge its internal state with any updates. This means that if a user interacts with the plot, by zooming or panning for example, any subsequent re-renders will lose this information unless it is captured and upstreamed via the onUpdate callback prop.
But the following two pieces of code behave identically:

• without state:

function StackedAreaChart({) {
  const layout = {
    showlegend: true,
    legend: {
      x: 0,
      y: -0.15,
      orientation: "h",
      traceorder: "normal",
      yanchor: "top",
    },
    autosize: true,
    margin: { pad: 10, b: 10, l: 40, r: 40, t: 80 },
  };

  const plotData = [...someData]

  return (
    <div style={{ height: 650 }} data-cy="stacked-area-chart">
      <Plot
        data={plotData}
        layout={layout}
        style={{ width: "100%", height: "100%" }}
        useResizeHandler
      />
    </div>
  );
}
export default StackedAreaChart;

• and with state:

function StackedAreaChart() {
  const [chart, setChart] = useState({
    data: [],
    layout: {
      showlegend: true,
      legend: {
        x: 0,
        y: -0.15,
        orientation: "h",
        traceorder: "normal",
        yanchor: "top",
      },
      xaxis: { range: [2000, 2019] },
      autosize: true,
      margin: { pad: 10, b: 10, l: 40, r: 40, t: 80 },
    },
    config: { responsive: true },
  });

  useEffect(() => {
    const plotData = [...someData];

    setChart((prevState) => ({
      ...prevState,
      data: [...plotData],
    }));
  }, [setChart, data]);

  return (
    <div style={{ height: 650 }} data-cy="stacked-area-chart">
      <Plot
        data={chart.data}
        layout={chart.layout}
        config={chart.config}
        style={{ width: "100%", height: "100%" }}
        useResizeHandler
      />
    </div>
  );
}
export default StackedAreaChart;

I can pan and zoom and then double click to return to its initial state on both codes. I can also modify the viewport width, making the chart to resize, while zoomed in and the chart still behaves perfectly.

I don't understand the warning in the documentation.
Am I doing something wrong ?

Das Issue nennt keine Repository-Datei und keinen Test; beginne damit, die Dokumentationspassage über die „dumb“-Komponente zu finden und sie mit den beiden React-Beispielen zu vergleichen. Reproduziere das gemeldete Pan-, Zoom-, Rerender- und Resize-Verhalten und kläre die Warnung oder dokumentiere die erwartete Unterscheidung, sobald das beabsichtigte Verhalten bestätigt ist.
