Vid 2047

It's one of the [major handlers that are registered](https://github.com/Wikia/app/blob/dev/extensions/wikia/WallNotifications/scripts/WallNotifications.globalNavigation.js#L32-L34) when wall notifications is initialized. It's used to fetch specific information about notifications for a wiki and then populates that html so the user can preview those notifications before clicking through to them. On the high level it may not look that interesting, but I think if you follow it down the stack it does some interesting stuff.
