Strange zoom after printing

Draw a fiew rectangles, go to print, put some scale, select vector output, PDF -> save as pdf.
After closing the print window you can see strange zoom behaviour - scroll to zoom out and the view jumps back to printed view. Closing and reopening rhino resolves the problem

I’ve retried this on my MBPro retina Mid 2012 and the problem is the same. Seems, this doesn’t happen if you print with raster output selected
