Localization

Hello 👋
I am having trouble with localization.
I have looked at plotly.js tests for some inspiration and I've seen that config.locale and config.locales are being set here and passed to newPlot fn. But it didn't really help me.

My Chart components looks like this:

import * as Plotly from 'plotly.js'
import * as csDictionary from 'plotly.js/lib/locales/cs.js'
import * as React from 'react'
import * as Plot from 'react-plotly.js'

Plotly.register(csDictionary)
Plotly.setPlotConfig({ locale: 'cs' })

const trace1 = {
  x: [0, 1, 2],
  y: [1, 1, 1],
  mode: 'lines+markers+text',
  name: 'Lines, Markers and Text',
  text: ['Text A', 'Text B', 'Text C'],
  textposition: 'top right',
  textfont: {
    family: 'sans serif',
    size: 18,
    color: '#1f77b4',
  },
  type: 'scatter',
}

class Chart extends React.Component {
  render() {
    return (
      <Plot
        config={{ locale: 'cs' }}
        data={[trace1]}
        layout={{
          width: 800,
          height: 400,
          title: 'A Fancy Plot',
        }}
      />
    )
  }
}
export default Chart

❓ Any ideas how to make this work?

Localization is crucial for me and it looks that it is somehow supported, but I just cannot figure how to set it up.

Thanks 🙏

Start by reproducing the localization setup shown in the issue, including Plotly.register, Plotly.setPlotConfig, config.locale, and the React Chart component. Compare the configured locale with the rendered chart and determine what change is needed for Czech localization to work; done means the chart's localized UI is visibly applied.
