Single steps are not rendered

React 18, Nextjs 12.3

import Steps from 'rc-steps';

import 'rc-steps/assets/index.css';


const { Step } = Steps;

const Tracking = () => {
  const [current, setCurrent] = useState(0);

  const onChange = (value) => {
    console.log('onChange:', current);
    setCurrent(value);
  };

  return (
    <>
      <Steps current={current} onChange={onChange}>
        <Step title="Step 1" description="This is a description." />
        <Step title="Step 2" description="This is a description." />
        <Step title="Step 3" description="This is a description." />
      </Steps>

      <Steps current={current} onChange={onChange} direction="vertical">
        <Step title="Step 1" description="This is a description." />
        <Step title="Step 2" description="This is a description." />
        <Step title="Step 3" description="This is a description." />
      </Steps>
    </>
  );
}

The single steps are not rendered within the Steps wrapper.

Start with the supplied React 18 and Next.js 12.3 reproduction, comparing the horizontal and vertical Steps examples. Trace how the Steps wrapper handles its Step children; done when single-step children render in both examples without regressing the shown multi-step behavior.
