Incorrect styling for foldable section

[johanbook]

I tried following the simple example and spinning up react-chart-editor, but it seems some styling is incorrect as seen in attached image.

I run the editor as

import "react-chart-editor/lib/react-chart-editor.min.css";

import * as React from "react";
// @ts-ignore // exists no types for `react-chart-editor`
import PlotlyEditor from "react-chart-editor";

// @ts-ignore // types not available for `plotly.js/dist`
import plotly from "plotly.js/dist/plotly";

const EDITOR_CONFIG = { editable: true };

...

export function DataExplorer({
  data,
  dataSourceOptions,
}: SomeProps): React.ReactElement {
  const [state, setState] = React.useState({
    data: [],
    layout: {},
    frames: [],
  });

  return (
    <PlotlyEditor
      advancedTraceTypeSelector
      config={EDITOR_CONFIG}
      data={state.data}
      frames={state.frames}
      layout={state.layout}
      dataSources={data}
      dataSourceOptions={dataSourceOptions}
      plotly={plotly}
      onUpdate={(data: any, layout: any, frames: any) =>
        setState({ data, layout, frames })
      }
      useResizeHandler
    />
  );
}

With versions

"react": "^17.0.1",
"react-dom": "^17.0.1",
"react-scripts": "^4.0.1",

Have I missed something?

@johanbook Could you try running it with React 16?

[johanbook]

I created a basic template with Create-React-App with React 17 and then managed to run this code without the issue so it's likely some issue in some other part of my code base

It seems is the same as https://github.com/plotly/react-chart-editor/issues/745 and the problem is to the css property box-sizing being set by a style library (Material UI). I fixed it by adding the equivalent of

.folder {
  box-sizing: "content-box"
}

to the global css. Works but not the prettiest
