Confirmed problem-Tableau Public navigation opening to bottom, new days ago

Hello, 

I can confirm this Public dashboard was working 100% correctly days ago. No structural updates at all. 

Now, when you click on a navigation button, the opening dashboards all will open to the bottom, not the top. This is 100% new and 100% consistent behavior as of a few days ago.  

Again, 100% confirm nothing was changed on my end and it was working days ago.
