New auto-hide dashboard's horizontal scroll-bar doesn't load always.

New auto-hide dashboard's horizontal scroll-bar doesn't load always.

Steps to reproduce:

1. Create as many forms as it would take to exceed the 3-column listing on the auto-hide dashboard, such that a horizontal scroll-bar would be required to reach all forms.
2. Logout and login (or just open a new tab).
3. Go to the "Forms" tab in the auto-hide Dashboard menu.

The horizontal scroll doesn't appear. However, when you navigate to other tabs ("Pages" or "Reports") and return to the "Forms" tab, the scroll bar starts to appear.

The problem occurs consistently.
