Titlebar should be apart of the header and not fade in/out on page change

[Jaeiya]

Currently, the Titlebar is imported on every page, which means there are no scenarios where the Titlebar isn't required in some capacity. If there aren't any very specific use-cases which modify how the Titlebar is added to the page, then in theory we should be able to affix it to the header.

If we can affix the Titlebar to the header then we can eliminate the awkward fade-in/fade-out of the Titlebar between page transitions. From a UX standpoint, it just doesn't look/feel right to see the entire bar disappear, when it includes menu interaction; the Titlebar acts as both a Menu bar and Titlebar.

Having vital site controls disappear between page transitions feels like a design flaw.
