Make it clear that sessionStorage and localStorage return the same
object each time, but a unique object per Document. (credit: pt) (whatwg
r2575)

When the setItem(), removeItem(), and clear() methods are called on a Storage object x that is associated with a local storage area, then in every HTMLDocument object whose Window object's localStorage attribute's Storage object is associated with the same storage area, other than x, a storage event must be fired, as described below.
