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.

Comece com a reprodução same_data vinculada e rastreie o caminho de atualização do componente Plot quando o layout muda, mas os dados são reutilizados. Compare as variações new_array e new_object para identificar o comportamento compartilhado. Considera-se concluído quando os ranges continuam sendo calculados e o zoom continua funcionando após clicar em Update Plot.
