Describe the bug
Consider you have tabbar with icons and counters. Then you are going to see how it looks on a small screen. Some tabs are being wrapped into ... section which trigger an aside panel. in that aside panel you can see wrapped tabs. But they missing icons and counter (contain only text)

To reproduce

1. Go to http://ui.tradeshift.com/v12/#components/header/tabs.html
2. Scroll until the 'Tabs icons' example and run it. You would be able to see the tab with an icon
3. Change browser width so it will wrap that tab into .... Click on it
4. See the 'Icon tab' does not have the icon

Do the same with "Tab counters" example on the same page

Expected behavior
tabs should be rendered with icons and counters
