title: Bootstrap tabs are greyed out when using browser back button
body: <p>In my project I'm implemented solution for Bootstrap tabs to work with browser back button. I've do that using window <code>popstate</code> event. Everything works perfectly, but the tab you back out of stays grayed/selected. This is a CSS issue? or maybe this is handled by browser?</p>
