           Summary: Should not box `this` in strict-mode getters
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: domenic at domenicdenicola.com


The following code should log "number" according to the ES5 spec, section 10.4.3 [1]:


Object.defineProperty(Object.prototype, "getMe", {
    get: function () {
        "use strict";
        console.log(typeof this);
    }
});

(0).getMe;


Instead it logs "object".
