 == Affects the Appearance > Menus admin page. ==

 When the viewport is larger than 900px, drag'n'drop works splendidly.
 '''Issue:''' none

 When the viewport goes < 900px, the left hand admin navigation shrinks as
 expected, I don't see any other visible changes.
 '''Issue:''' now when you try to drag'n'drop menu items vertically in the
 list, they tend to jump to the right and become sub-items. A fairly
 dramatic leftwards translation will override this.

 When the viewport goes < 800px, the whole page layout switches from two
 columns to one.
 '''Issue:''' now when you try to drag'n'drop menu items vertically in the
 list, the viewport scrolls down quite rapidly, and they become sub-items.
 No amount of leftwards translation will override this.
 Holding the mouse button and trying to scroll up results in the viewport
 scrolling down again.

 '''Suspect:''' drag'n'drop js doesn't know that it's possible for the
 layout the respond to the viewport size.
