1. Open page http://bootstrapdocs.com/v2.0.4/docs/components.html
2. Inspect div.subnav element (white menu)
3. Scroll to the middle of page until second menu (white) will be fixed. New class .subnav-fixed will be added to element, you can see it in source code, tags path at the bottom display it correct.
4. Now scroll to the top, source code will display correct classes for menu - .subnav, but tags path will be as it was - .subnav.subnav-fixed
