How are you using Babel?

@babel/eslint-parser

Input code

class State {
  @tracked depth = 0;
}

Configuration file name

No response

Configuration

module.exports = {
  root: true,
  parser: '@babel/eslint-parser',
  parserOptions: {
    ecmaVersion: 'latest',
    sourceType: 'module',
    requireConfigFile: false,
    babelOptions: {
      plugins: [
        ['@babel/plugin-proposal-decorators', { decoratorsBeforeExport: true }],
      ],
    },
  },
}

Current and expected behavior

Expected eslint to run without issues.
Actual: error 'tracked' is defined but never used no-unused-vars

Reverting @babel/eslint-parser to 7.23.3 fixes the issue.
