description: Tests that the option useGrouping is processed correctly.
info: |
  The "Intl.NumberFormat v3" proposal contradicts the behavior required by the
  latest revision of ECMA402. Likewise, this test contradicts
  test-option-useGrouping.js. Until the proposal is included in a published
  standard (when the tests' discrepancies can be resolved), implementations
  should only expect to pass one of these two tests.
features: [Intl.NumberFormat-v3]
