css react styled-components JavaScript

I'm experiencing an issue where hover styles are not being applied to child elements of a dynamically generated component in my React 17 application. I'm using styled-components for styling, and the hover effect should change the background color of a child div when the parent is hovered over. However, it only works if the parent is directly defined in JSX and does not seem to trigger for elements rendered conditionally based on state. Here's a simplified version of my code: ```jsx import React, { useState } from 'react'; import styled from 'styled-components'; const Parent = styled.div` padding: 20px; background-color: lightgray; &:hover > div { background-color: yellow; } `; const Child = styled.div` width: 100px; height: 100px; background-color: red; `; const App = () => { const [showChild, setShowChild] = useState(false); return ( <Parent onMouseEnter={() => setShowChild(true)} onMouseLeave={() => setShowChild(false)}> {showChild && <Child />} Hover over me! </Parent> ); }; export default App; ``` When I hover over the `Parent` component, I expect the `Child` component's background color to change to yellow, but it doesn't happen. I’ve tried using `!important` in the styled-components definition and also modifying the CSS selector to `&:hover div`, but neither approach worked. I've verified that the hover effect works when `Child` is always rendered, but not when it's conditionally rendered. Is there a specific way I should handle hover effects for dynamically added children in styled-components? Any guidance or solutions would be appreciated!
