I'm going to put this here for future reference: we do not need to add similar abilities to CloseEvent and ErrorEvent because closing a WebSocket is a very, very cold path & error paths are inherently slow and also cold paths.

MessageEvent, on the other hand, is instantiated for every single WebSocket frame received, and also used in Node's Worker.
