Refs on the mounted root element do not appear to be triggered. Is this expected behaviour?

  it('triggers refs on child elements', (done) => {
    mount(<div><span ref={(c) => done()}/></div>);
  });

  it('triggers refs on root elements', (done) => {
    mount(<span ref={(c) => done()}/>);
  });

Current behavior

The child elements test passes, but the root element test fails

Expected behavior

Both tests should pass
