Tested the latest patch #55 for both LTR and RTL directions and I agree with @yoroy. By floating the view mode select list to the right in LTR, or to the left in RTL pushes the view mode out and it becomes invisible (when the toolbar is in vertical mode). Attaching SS.
As per my views, we should keep the select list aligned with the "back to content editing" button for desktop, and for mobile layout select list will appear just below the button as done in patch #34.
