title: Tailwindcss group-hover not working on border color
body: <p>When I hover over a navigation item, I want a span border color to be changed. The group-hover does nothing...</p>
  <p>Is this just not implemented in Tailwindcss yet?</p>
  <pre class="lang-html prettyprint-override"><code> &lt;a class=&quot;group px-4 py-2 hover:bg-white
              hover:text-primary transition-colors duration-300
              rounded-sm&quot;
       :href=&quot;route&quot;&gt;
      &lt;span class=&quot;pb-1 border-b border-white group-hover:border-black&quot;&gt;
          &lt;slot/&gt;
      &lt;/span&gt;
    &lt;/a&gt;
  </code></pre>
  <p>I obviously can do this by writing css like this, but tailwind should be able to do this, right?</p>
  <pre class="lang-css prettyprint-override"><code>a:hover span {
    border-color: black;
  }
  </code></pre>
