findDOMNode is deprecated in StrictMode

[ThomasThelen]

I found the following error in the console and tracked it down to react-cytoscapejs.

 state = {
    w: 0,
    h: 0,
    elements: []
  }

  render() {
    return (
      <div className="home-body">
        <div className="home-graph">
        <CytoscapeComponent
            elements={this.state.elements}
        />
   )
}

react-dom.development.js:86 Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of t which is inside StrictMode. Instead, add a ref directly to the element you want to reference. Learn more about using refs safely here: https://reactjs.org/link/strict-mode-find-node

This is fixed by PR https://github.com/plotly/react-cytoscapejs/pull/53, but it is not yet pushed to the npm registry.

I fixed it in my local project by pointing the package to that commit: yarn add https://github.com/plotly/react-cytoscapejs#ca1cf24c01af69a96f4002e1adc9ddae44b67ce5.

v2.0.0 published last week contains this fix. Apologies for the confusion and delay.
