[NavigationView] Item states not working when there are less than 6 menu items

[steamedham544]

Description: The ripple animation isn't shown when trying to select an item when one is already selected. This happens if there are less than 6 menu items defined in xml. Adding another item to the menu xml fixes this issue.

Expected behavior: The non-selected items should highlight when touched if an item is already selected.

How to reproduce:

1. Create a menu xml with 5 items and set it as your menu in NavigationView.
2. Add an NavigationView.setNavigationItemSelectedListener
3. Run the app and select an item. Ripples and states work perfectly fine here.
4. Long press a different item. The touched state doesn't show.
5. Repeat with 6 menu items and the touched state works perfectly.
