useRef.current.contains不是一个函数

import React, { useRef } from 'react';

function MyComponent() {
  const element1Ref = useRef(null);
  const element2Ref = useRef(null);

  const handleCheckContains = () => {
    if (element1Ref.current && element2Ref.current) {
      const isContains = element1Ref.current.contains(element2Ref.current);
      console.log('Element 2 is contained within Element 1:', isContains);
    }
  };

  return (
    <div>
      <div ref={element1Ref}>Element 1</div>
      <div ref={element2Ref}>Element 2</div>
      <button onClick={handleCheckContains}>Check Contains</button>
    </div>
  );
}
