带有默认检查的React单选按钮行为奇怪

import React, { useState } from 'react';

const RadioButtonGroup = () => {
  const [selectedOption, setSelectedOption] = useState('');

  const handleOptionChange = (event) => {
    setSelectedOption(event.target.value);
  };

  return (
    <div>
      <label>
        <input
          type="radio"
          value="option1"
          checked={selectedOption === 'option1'}
          onChange={handleOptionChange}
        />
        Option 1
      </label>
      <label>
        <input
          type="radio"
          value="option2"
          checked={selectedOption === 'option2'}
          onChange={handleOptionChange}
        />
        Option 2
      </label>
    </div>
  );
};

export default RadioButtonGroup;

import React, { useRef, useEffect } from 'react';

const RadioButtonGroup = () => {
  const option1Ref = useRef();
  const option2Ref = useRef();

  useEffect(() => {
    option1Ref.current.checked = true;
  }, []);

  return (
    <div>
      <label>
        <input type="radio" ref={option1Ref} value="option1" />
        Option 1
      </label>
      <label>
        <input type="radio" ref={option2Ref} value="option2" />
        Option 2
      </label>
    </div>

};

export default RadioButtonGroup;
