PowerBI Service - Hide sidebar in full screen mode

I'm experiencing the same issue as OP. The app nav bar was previously not present in full screen mode, but now is.  And this is relatively new behavior.

I'd like for the app navigation bar to be removed from full screen, as well.  The intention for full screen should be for the report to be the entire focus of the screen.  The nav bar takes up too much space and is distracting, particularly in a presentation setting.  If I want to navigate away, I would simply exit full screen mode first.

When we work in PowerPoint, we don't have menu options in Presentation mode, right?  Power BI should reflect the same philosophy.
