            Bug ID: 242342
           Summary: Object.prototype.toString.call for a revoked Proxy has
                    the wrong error message
           Product: WebKit
           Version: Safari 15
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ljharb at gmail.com

`var r = Proxy.revocable({}, {}); r.revoke(); Object.prototype.toString.call(r.proxy)` produces an error with a message "Array.isArray cannot be called on a Proxy that has been revoked", which should appear with `Array.isArray(r.proxy)` but should not appear with `Object.prototype.toString.call(r.proxy)`.
