2016:11 Is The New Synth Rack Opening/Closing Correctly?

I like having the streamlined, separate synth rack...
 
But maybe I'm doing something wrong as it seems no matter what I do, it always opens docked to the right...
 
Is anyone else seeing this?
 
I'm gonna search to see if something is anchoring it there?
 
Ahhh... I see. If I use Ctrl-Shift-S to toggle open/close, it reappears where I prefer it (undocked). If I use the close button (right-corner-X) to close it, it returns to right-side-docked...
 
I like being able to toggle it, but Should it be this way from the close button?
