1) Two simple link items in sidenav menu
2) Click one of the items to make it active (lets name it the first clicked menu item).

Expected behavior: When you click other item, the first clicked menu item should be unmarked as active and currently clicked should be marked as active.

Current behavior: Both items are marked as active.

Observations: When both are marked as active, when you click the first clicked menu item and the other one again, then the first clicked menu item is unmarked as active.
