When accessing the Roles Admin Portlet, if a User signs-out or times-out and tries to access features, the user will be given a sign-in screen inside the portlet and if the User signs-in, the UI fails. See screenshots.

Steps to reproduce:

1. Sign in as Admin
2. Navigate to Control Panel -> Users -> Roles
3. Select the Guest Role
4. Click on the Define Permissions tab.
5. Open another tab in your browser and navigate to the portal. (You should be logged in).
6. From that tab sign-out.
7. Go back to the original tab and select Site Administration -> Content -> Bookmarks

Expected Result:
The user is navigated to a Sign-in portlet.
Signing in from this portlet will return the user to the current page.

Actual Result:
The Sign-in portlet opens inside a frame in the Roles Admin Portlet.
 
Attempting to sign-in navigates the User to the Role page where the UI has failed.
