This is also visible in classical office planning. Nowadays people seems to have forgotten it. Look in an old office, on what side of the table is the window in most of the rooms? If the occupant is left-handed, what side is the window now? The desktop lamp? This is not a new problem, lights are supposed to be on the left side of a right-handed person when writing, otherwise you will shadow your paper while writing. Same goes with the mouse cursor, when right-handed, it's natural that it would point to the left.
