v4 alpha - col-*-* and hidden-*-down break on different resolution

[wstoettinger]

Hey There,
so I got this code:

    <div class="hidden-xs-down col-sm-12">
      <div class="card">
        <div class="card-block">
          <h4 class="card-title">Some Title</h4>
          <p class="card-text">Some quick example text 
            to build on the card title and make up the bulk 
            of the card's content.</p>
        </div>
      </div>
    </div>
    <div class="col-xs-12 col-sm-6 col-lg-4">
      <div class="card">
        <div class="card-block">
          <h4 class="card-title">Some Other Title</h4>
          <p class="card-text">Some quick example text 
            to build on the card title and make up the bulk 
            of the card's content.</p>
        </div>
      </div>
    </div>
   <!-- further similar blocks here -->

and when I was testing the layout in Chome Dev Tools, the breaking seemed a bit odd, so I took a closer look. I found out that the first div is still showing while the other divs already "broke" to col-xs-12 at exactly 543px. It's fairly improbable that someone is using a page with exactly that resolution, but still I think it shouldn't be that way.

best

This was opened a long time ago and there have been significant changes to v4 since then. If you're still having this problem, can you please open a new issue with a jsbin demo-ing the bug? Thanks!
