-`<paper-icon-item>` is a convenience element to make an item with icon. It is a non interactive list
-item with a fixed-width icon area, according to Material Design. This is useful if the icons are of
-varying widths, but you want the item bodies to line up. Use this like a `<paper-item>`. The child
-node with the attribute `item-icon` is placed in the icon area.
