* Renders an object. An object is represented by a list of its
* properties enclosed in curly brackets.
*
* This rep receives only an `object` property which is the actual object to render a
* preview for.
* This is used by JSON Viewer and Netmonitor to render JSON objects fetched from the
* frontend, which doesn't involve any Object Actor/Front or any grip (which is the
* object actor's form).
* In the console and debugger, plain JS objects are rendered via GripRep (in grip.js),
* as they involve an object actor.
