Bug found in the World of Warcraft mobile companion app. Appears to be cosmetic/UI.
After viewing a character and tapping on an Item to view the details, a highlight on the item slot remains after closing the details window. A yellow highlight remains on the bottom of the item slot and the item icon appears raised in the slot window upon return to the main character paperdoll screen.
