 // An interface that controls a RenderViewContextMenu instance from observers.
 // This interface is designed mainly for controlling the instance while showing
 // so we can add a context-menu item that takes long time to create its text,
 // such as retrieving the item text from a server. The simplest usage is:
 // 1. Adding an item with temporary text;
 // 2. Posting a background task that creates the item text, and;
 // 3. Calling UpdateMenuItem() in the callback function.
 // The following snippet describes the simple usage that updates a context-menu
 // item with this interface.
