ranges does not get computed when same data is used but Plot is updated

If layout is change but data stays the same, Plot's ranges are not computed correctly.

Consider this React component

(full project can be found here: https://github.com/saad-learns/react-plotly/tree/same_data

function App() {
  const [plotUpdated, setPlotUpdated] = React.useState<number>(0);
  const [plotParams, setPlotParams] = React.useState<PlotParams>({
    data: [
      {
        x: [-3, -2, -1, 0, 1, 2, 3],
        y: [
          -0.1411200080598672, -0.9092974268256817, -0.8414709848078965, 0,
          0.8414709848078965, 0.9092974268256817, 0.1411200080598672,
        ],
      },
    ],
    layout: {},
  });

  const updatePlot = () => {
    setPlotParams((prevState) => ({
      data: prevState.data,
      layout: {},
    }));
  };

  return (
    <div className="App">
      <div style={{ padding: 10 }}>
        <button onClick={updatePlot}>Update Plot</button>
      </div>

      <Plot
        data={plotParams.data}
        layout={plotParams.layout}
        onUpdate={() => setPlotUpdated((prevState) => prevState + 1)}
      />

      <div>Plot updated: {plotUpdated}</div>
    </div>
  );

At the start, ranges are calculated correctly. You can verify that with React Dev Tool's Component tab:

Or you can use Zoom In and Zoom Out button to verify that zooming is working.

But if you click on the Update Plot button, the ranges are not computed, in fact they get removed:

Thereafter, zooming does not work.

Here, updatePlot will use the same data object, but makes use of a new layout. According to https://github.com/plotly/react-plotly.js#refreshing-the-plot Plot should be refreshed, and it does, but ranges are no longer computed correctly.

There are other variation of the above issue:

1. Use a new array but same previous data element: https://github.com/saad-learns/react-plotly/blob/new_array/src/App.tsx
2. Use a new array, and a new element but with same previous data: https://github.com/saad-learns/react-plotly/blob/new_object/src/App.tsx

where ranges are not computed properly.

Beginne mit der verknüpften same_data-Reproduktion und verfolge den Aktualisierungspfad der Plot-Komponente, wenn sich das Layout ändert, die Daten aber wiederverwendet werden. Vergleiche die Varianten new_array und new_object, um das gemeinsame Verhalten zu ermitteln. Als abgeschlossen gilt die Änderung, wenn die ranges weiterhin berechnet werden und das Zoomen nach dem Klicken auf Update Plot weiterhin funktioniert.
