使用Antd Popover组件时，如果鼠标悬浮时间过长，应用程序可能会冻结。解决这个问题的方法是在Popover组件中加入mouseLeaveDelay属性，使鼠标离开后一段时间后组件才关闭。示例如下：

import React, { useState } from "react";
import { Button, Popover } from "antd";
import "antd/dist/antd.css";

const App = () => {
  const [visible, setVisible] = useState(false);
  const [content, setContent] = useState("");

  const handleVisibleChange = (visible) => {
    setVisible(visible);
  };

  const handleClick = () => {
    setContent("Popover content");
    setVisible(true);
  };

  return (
    

      Show Popover
      
        
hover me
      
    
  );
};

export default App;
