           Summary: Sorting a non-array creates propreties (spec-violation)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: lrn at chromium.org


Sorting a sparse non-array object will create properties with the value
"undefined" instead of deleting existing properties.

Example:
 [].sort.call({length:5,2:42}).hasOwnProperty(2)
The resulting object has the form {length:5, 0:42, 2:undefined}. According to
the specification, the "2" property should not exist.
