Small UI issue when expanding last element of AS

Steps to reproduce:

• create a space using the Space Dashboard Template
• create a page with several modifications (comments, etc .. just to be logged by the AS)
• when you are in the Space.WebHome and expand the last element in the AS, you will see a scroll bar appears.

Setting the css propriety overflow form #xwikicontent to visible works, but not sure this is the best fix
