title: bootstrap 4, cursor doesn't change when hovering over a button but does on anchors
body: <p>I'm using bootstrap 4 alpha, and it seems that the cursor on buttons has been removed for buttons but not anchor tags. example on the bootstrap site. </p>
  
  <p><a href="https://v4-alpha.getbootstrap.com/components/buttons/" rel="noreferrer">https://v4-alpha.getbootstrap.com/components/buttons/</a></p>
  
  <p>In my application i have a form, with two buttons, one is to post to the form and the other is to redirec to another page. The input doesn't display the cursor but the anchor does. I know i can create a custom css class, but is there a reason why this has been removed or is it an issue with the current alpha version? </p>
  
  <pre><code>&lt;input type="submit" value="Sign In" class="btn btn-primary" /&gt;
  &lt;a role="button" href="@Url.Action("Register", "Account")" class="btn btn-secondary"&gt;Register Now&lt;/a&gt;
  </code></pre>
