{
  "rules": {
    "@typescript-eslint/require-await": "error"
  }
}

async function* foo() {
  await Promise.resolve()
  yield 1
}
async function* bar() {
  yield* foo()
}

Expected Result
No error. bar has to be async because it delegates to foo, which is async.

Actual Result
Error: Async generator function has no 'await' expression.
