What version of eslint-plugin-vue and vue-eslint-parser are you using?

• eslint-plugin-vue@10.4.0

What did you do?

see https://github.com/vuejs/eslint-plugin-vue/actions/runs/17426870338/job/49476333521?pr=2920 and https://github.com/vuejs/eslint-plugin-vue/blob/master/tests/fixtures/script-indent/ts-enum-member-01.vue:

Configuration

{"languageOptions": {"parserOptions": {"parser":"@typescript-eslint/parser"}}}

<script lang="ts">
enum Direction {
  // comment
  Up = 1,
  // comment
  Down,
  Left
    = 2,
  [
    Right
  ] =
    3,
}
</script>

What did you expect to happen?

This test case used to pass with https://github.com/typescript-eslint/typescript-eslint/releases/tag/v8.41.0, but started to fail when @typescript-eslint/parser was updated to v8.42.0.

What actually happened?

Parsing error: Computed property names are not allowed in enums.

Note that TypeScript itself complains about the same problem: https://typescript-eslint.io/play#ts=5.9.2&fileType=.tsx&code=KYOwrgtgBAIglgJ2AYwC5wPYigbwFBRQD0RUyGEEoqBUAqgA5QC8UAjADS0lkVUg1CMDAHcQXQgBlgAM0EsoAJglQA2rQBKcAOYALeQF0WtAMxcAvniA&eslintrc=N4KABGBEBOCuA2BTAzpAXGYBfEWg&tsconfig=N4KABGBEDGD2C2AHAlgGwKYCcDyiAuysAdgM6QBcYoEEkJemy0eAcgK6qoDCAFutAGsylBm3TgwAXxCSgA&tokens=false
