The new Outlook search in the title bar is disconnected from the content it searches

This just changed for me within the last few days.  Horrible UI choice.  The search bar makes all my Outlook folder windows look the same... can't tell which folder the window content is for anymore (or even which application the window belongs to, for that matter, if only the title bar is visible).  Completely obliviates the purpose of the title bar, as now no window-identifying description is visible in the title bar.  Seriously, all I see in the window title bar is the search input box, even though there is space for a window title.

Tried to provide feedback/vote at user voice (https://outlook.uservoice.com/forums/322590-outlook-2016-for-windows/suggestions/39046513-search-at-the-top-option) but they have shut it down.

I am an IT professional and have designed GUIs myself, but it is hard to fathom what the product managers were thinking when this design decision was made.  Maybe they need to read "The Inmates Are Running the Asylum" (seriously, this is a book about interface design).  Developers love to overload UIs with functionality, to the point it gets in the way of usability, or to drive the design by what is easiest to implement, rather than what will be most user-friendly.
