While most all assets are using retina, if you attemp to edit a menu under appearance > menus and then click on the arrow to see more info about a menu item the arrow used is non retina
Attached patch also prefixes the :hover variant of the link, I have no idea why it's not prefixed, but with such a generic class name, I thought it best to add it.
