ie11에서 onMouseEnter가 중첩되었을때 event를 하위 컴포넌트까지 pass 하지 않음.

import React from 'react';

const Btn = () => {
  return (
    <button onMouseEnter={() => {
      console.log('Btn onMouseEnter');
    }}>클릭</button>
  )
}
export default function Component() {
  return (
    <>
      <div onMouseEnter={() => {
        console.log('Component onMouseEnter');
      }}
      >
        <Btn />
      </div>
    </>
  )
}
