[Webkit-unassigned] [Bug 142933] Redefining a property should not change its insertion index (Object.keys order)

--- Comment #3 from Joseph Pecoraro <joepeck at webkit.org> ---
Doesn't appear to be any particular reason. The implementation has always had a delete since Object.defineProperty was first added for ES5 support years ago. ES5 has the update wording here.
