>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.
container.firstChild.hasAttribute('suppressContentEditableWarning'),
      ).toBe(false);
      expect(
        container.firstChild.hasAttribute('suppressHydrationWarning'),
      ).toBe(false);
    });
    it('should skip dangerouslySetInnerHTML on web components', () => {
      var container = document.createElement('div');
      ReactDOM.render(
        <my-component dangerouslySetInnerHTML={{__html: 'hi'}} />,
        container,
      );
      expect(container.firstChild.hasAttribute('dangerouslySetInnerHTML')).toBe(
        false,
      );
      ReactDOM.render(
        <my-component dangerouslySetInnerHTML={{__html: 'bye'}} />,
        container,
      );
      expect(container.firstChild.hasAttribute('dangerouslySetInnerHTML')).toBe(
        false,
      );
    });
    it('should render null and undefined as empty but print other falsy values', () => {
      var container = document.createElement('div');
      ReactDOM.render(
        <div dangerouslySetInnerHTML={{__html: 'textContent'}} />,
        container,
      );
      expect(container.textContent).toEqual('textContent');
