Describe the Bug

.good {
  :global {
    a {
      color: red;
    }
  }
}

import styles from './page.module.scss'
function Test(){
  return <div className={styles.good}></div>
}

throw error

Expected Behavior

In NextJS14, I can use: global， But in 15, it will throw an error。
I don't know how to use it in version 15: global， How can I modify the component style of the current page if it cannot be used
