/**
 * Design notes regargind auto-resize of the tweet:
 *
 * - setTweetId call on the manager results into a loadTweet method call in TweetView
 * - loadTweet method command's results (Tweet) loaded
 * - as soon as that happens, a onSizeChanged event gets posted to the manager
 * - the manager applies the new size via the UIManager
 * - shadow node re-calculates the layout and passes on the loaded Tweet to the actual tweet, along with the measured layout
 *
