--- "@logto/experience": patch --- skip non-object messages in the native environment In the `WKWebView` of new iOS versions, some script will constantly post messages to the window object with increasing numbers as the message content ("1", "2", "3", ...). Ideally, we should check the source of the message with Logto-specific identifier in the `event.data`; however, this change will result a breaking change for the existing native SDK implementations. Add the `isObject` check to prevent the crazy messages while keeping the backward compatibility.
