Form Designer: moving multiple controls with keyboard affects their dimensions.

Original Reporter info from Mantis: ptvs

Description:

When you move selected controls on the form designer, and then unselect some of them so that selection shrinks, and move the selection with keyboard, then selected controls's width and height will shrink proportionally every time you press the Ctrl+Arrows.
This not happens if you add some controls back after you unselected them.

Steps to reproduce:

1. Select three or more controls on the form.
   
2. Move selected controls with keys or mouse.
   
3. Unselect any control at the edge of overall selection box so that it shrinks.
   
4. Move selected controls with Ctrl+Arrows.
