>Warning: A component is `contentEditable` and contains `children` managed by React. It is now your responsibility to guarantee that none of those nodes are unexpectedly modified or duplicated. This is probably not intentional.

It would help heaps if I would know _which_ component is causing this.
ReactDOM.render(<div />, container);
      expect(container.firstChild.innerHTML).toEqual('bonjour');
    });
    it('should reset innerHTML when switching from a direct text child to an empty child', () => {
      const transitionToValues = [null, undefined, false];
      transitionToValues.forEach(transitionToValue => {
        var container = document.createElement('div');
        ReactDOM.render(<div>bonjour</div>, container);
        expect(container.firstChild.innerHTML).toEqual('bonjour');
        ReactDOM.render(<div>{transitionToValue}</div>, container);
        expect(container.firstChild.innerHTML).toEqual('');
      });
    });
    it('should empty element when removing innerHTML', () => {
      var container = document.createElement('div');
      ReactDOM.render(
        <div dangerouslySetInnerHTML={{__html: ':)'}} />,
        container,
      );
      expect(container.firstChild.innerHTML).toEqual(':)');
      ReactDOM.render(<div />, container);
      expect(container.firstChild.innerHTML).toEqual('');
    });
    it('should transition from string content to innerHTML', () => {
      var container = document.createElement('div');
      ReactDOM.render(<div>hello</div>, container);
      expect(container.firstChild.innerHTML).toEqual('hello');
      ReactDOM.render(
        <div dangerouslySetInnerHTML={{__html: 'goodbye'}} />,
        container,
