Throwing with ESLint 9 and flat config

See meduzen/datetime-attribute/pull/128.

Using eslint@9.0.0 and eslint-plugin-vitest@0.4.2-beta.3, it throws on the first expect encountered:

> pnpm exec eslint

Oops! Something went wrong! :(

ESLint: 9.0.0

eslint.config.js:

import tseslint from 'typescript-eslint'
import js from '@eslint/js'
import vitest from 'eslint-plugin-vitest'

export default tseslint.config(
  js.configs.recommended,
  {
    files: ['**/*.js'],
    languageOptions: {
      sourceType: 'module',
      ecmaVersion: 2024,
      parserOptions: {
        ecmaFeatures: {
          impliedStrict: true,
        },

    },

    // (first parameter of a rule) 0: off, 1: warning, 2: error
    rules: {
      // my rules…

  },

    plugins: { vitest },
    rules: {
      ...vitest.configs.recommended.rules,
    },
    languageOptions: {
      globals: {
        ...vitest.environments.env.globals,
      },
    },
  },
)

Note: the issue is the same when not using tseslint.config or when only keeping the config entry containing plugins: { vitest }.
