Can you merge with https://codereview.chromium.org/199283002/
That CL removes the code in the ifdef completely :)

Will wait for that patch to land and then rebase to ToT and re-upload.

   // NOTE(pkotwicz): Animating to immersive fullscreen does not look good. When
   // switches::UseImmersiveFullscreenForAllWindows() returns true, most windows
   // can be put into immersive fullscreen. It is not worth the added complexity
   // to only animate to fullscreen if the window is put into immersive
   // fullscreen.
