<App> was created without expected data property 'event' warning in dev mode

[Kiho]

REPL
event should be white listed in svelte but above REPL generate code block

function App(options) {
	this._debugName = '<App>';
	if (!options || (!options.target && !options._root)) throw new Error("'target' is a required option");
	init(this, options);
	this._state = assign({}, options.data);
	if (!('cats' in this._state)) console.warn("<App> was created without expected data property 'cats'");
	if (!('event' in this._state)) console.warn("<App> was created without expected data property 'event'");
.....
}

and then show warning in browser console when running in dev mode .
<App> was created without expected data property 'event'
