Selections of multiple items don't have proper undo functionality after running into a "wall"

Create several items scattered about. Select all of them, and move them with the arrow keys all the way to the left till the left most item hits the wall. Now press shift left several more times. This will cause the items to move out of sync, which would be fine in general, but now press undo. The items now ALL move back to the right, including the one that's been banging against the wall for several "left" presses, making it so it's impossible to undo.
