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produces an error with a message "Array.isArray cannot be called on a Proxy that has been revoked", which should appear with `Array.isArray(r.proxy)` but should not appear with `Object.prototype.toString.call(r.proxy)`.

Which version of Safari might this appear in? 16.2 still has the issue.

Safari 16.3 also still has this issue.

This continues to be a problem in Safari 17.1.
