Maximizing a portlet supersedes focusing on a fragment.

Fixes problem where the focus-on-a-fragment feature had broken maximizing portlet when portlet is a favorite or member of a favorite collection.

Without this fix:
1. View a collection of favorites, by clicking its name from the Favorites portlet.
2. Maximize a portlet, via e.g. the Options menu available from its title bar.
3. Observe failure to focus the portlet.  Sad panda.

With this fix:

2. Maximize a portlet, via e.g. the Options menu available from its title bar.
3. Observe focus on the maximized portlet.  Happy badger.
