            Bug ID: 205769
           Summary: JSON.parse should lookup prototype chains during
                    revival
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Trivial
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: shvaikalesh at gmail.com

ECMA262: https://tc39.es/ecma262/#sec-internalizejsonproperty (step 1)
Test262:
  https://test262.report/browse/built-ins/JSON/parse/reviver-array-get-prop-from-prototype.js
  https://test262.report/browse/built-ins/JSON/parse/reviver-object-get-prop-from-prototype.js

Currently, JSC gets only own properties. ChakraCore fails array test, yet passes the object test.
Related steps of InternalizeJSONProperty were not normatively changed since ES5.
