description: >
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.
