<p dir="auto">Just before the 3.1 release, having div class="visible-sm visible-xs" together on a div would show the div when it hit both breakpoints.  Now, it only works on one breakpoint.  They both work individually, but when there's more than one declared on a div, only one class gets triggered. Does the same for hidden.</p>
<p dir="auto">I checked the issues log and didn't notice this.  Hopefully i am not the only one finding this.</p>
