Sequence-Diagram: User is already logged in and refreshes the browser - (2)

Kind a weird the workflow in debug mode goes when authentication was successfully done and an apparently simply looking instruction "self.navigateToHome is called". The very first sequence of that shows some "magic" infrastructure diagram boxes that are "used" or called through the way down showing the home screen. I have to dissect this apparently knockout.js - based stuff in next Iteration.
