nav-justified not working within navbar

Created by: robinchrist

Hello, It seems like nav-justified and nav-fill are not working together with navbar. Example: https://jsfiddle.net/wq16antm/ Tested with Chrome 56.0.2924.76 on Ubuntu 16.04

The Bootstrap justified-nav example (http://v4-alpha.getbootstrap.com/examples/justified-nav/) seems to be pretty broken as it is permanently collapsed (shouldn't the whole toggle-stuff disappear when the screen is big enough?). I just want justified pills within a fixed-top navbar collapsing at medium level...
