Why is BootStrap 4 Progress Bar Not Animating
<p>I'm looking at the documenation on <a href="http://v4-alpha.getbootstrap.com/components/progress/" rel="nofollow">http://v4-alpha.getbootstrap.com/components/progress/</a></p>

<p>It does not work there, and it does not work on the site I am building.</p>

<p>Has anyone else encountered this or is this a bug?</p>
