This effects all versions.
When a hopper puts items into a chest they are not put into the correct spot. For example, if you have a zombie farm and the items are properly sorted in the chest, the hopper will not place them with incomplete stacks of that item. It will start a new stack Every time the original stack has something placed next in line to it. Look at the image below to see what I am talking about.

Hoppers fill containers in the order of their available slots. The order of the slots in containers is left to right, then row by row top to bottom. It's the same way most western languages are written and read. It's also the same way the player inventory is ordered.
If you think containers should be ordered differently you can make a feature request for that on the Feedback Site.
