Many thousands of instance Favorite rights are available in Clarity UI.
Example: Favorite menu link items Favorites Menu 5000000.union.favLeftNav
Note: Same happens if you add individual Instance rights to a Resource - Portlet View
Steps to Reproduce:
Expected Results: The Favorite Menu portlet instance rights should NOT be available to be added to other users as instance right.
Actual Results: All the Favorite Menu access rights are available in the list, including those for inactive users, the list may be tens of thousands just due to this.
