>+        When provided a way to access the `WI.RemoteObject` for the given preview, add various mouse
>+        event listeners that highlight the corresponding DOM node.

>+        Implement various ways of getting the `WI.RemoteObject` for a given preview.
>+         - When the preview is for the actual `WI.RemoteObject`, simply return it
>+         - If the preview is a property of the main object, get the `WI.RemoteObject` for that property
