  Previously implementation-defined aspects of Array.prototype.sort.
info: |
  Historically, many aspects of Array.prototype.sort remained
  implementation-defined. https://github.com/tc39/ecma262/pull/1585
  described some behaviors more precisely, reducing the amount of cases
  that result in an implementation-defined sort order.
