Code Review for Job #19775 - Workitem available at https://www.worklist.net/19775
Please move this block of code to a `NewWorklist.initMentions` method -or similar name- in `newworklist.js` and call that new method from `NewWorklist.init`, it will be called on each page's initialization in a more controlled initialization flow. No need to do the `$(document).ready();` then. You'll need to change `ajaxUrl` too accordong to my previous request.
