研究方向
The issue shows that overlayRef and contentRef are undefined in componentDidMount. Investigation should focus on where the refs are assigned in the component's lifecycle. The linked codesandbox demonstrates the problem. The solution likely involves assigning refs properly in the render method or using callback refs instead of relying on componentDidMount.
