           Summary: Array.prototype.sort is not quite stable
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: richard.gibson at gmail.com


The results of sorting length-N arrays for sufficiently large N appear to differ from a stable sort only at indices 0, 1, and N/2. It would be very convenient for Sizzle and jQuery if the sort were made fully stable, *especially* if such change lands in 537.32 so there's no release in which #108274 is fixed but this is not.
