title: aria-* attributes do not have valid values
body: <p>I'm running tests with Lighthouse on <a href="https://www.localizzazionemezzi.it/la-piattaforma" rel="nofollow noreferrer">this page</a>.</p>
  
  <p>When it comes to Accessibility, it keeps give me this error:</p>
  
  <blockquote>
    <p>[aria-*] attributes do not have valid values.<br>
    Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid values.</p>
  </blockquote>
  
  <p>The code that causes that error is:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;button role="tab" aria-selected="true" aria-controls="v-pills-home" id="v-pills-home-tab" class="nav-link active" data-toggle="pill" href="#v-pills-login"&gt;&lt;img src="./images/come-funziona/iconLogin.png" width="60" alt="login"&gt; Login&lt;/button&gt;
  
  &lt;button role="tab" aria-selected="false" aria-controls="v-pills-profile" id="v-pills-profile-tab" class="nav-link" data-toggle="pill" href="#v-pills-localizzazione"&gt;&lt;img src="./images/come-funziona/iconLocalizzazione.png" width="60" alt="localizzazione mezzi"&gt; Localizzazione&lt;/button&gt;
  
  &lt;button role="tab" aria-selected="false" aria-controls="v-pills-messages" id="v-pills-messages-tab" class="nav-link" data-toggle="pill" href="#v-pills-badge"&gt;&lt;img src="./images/come-funziona/iconBadgeRFID.png" width="60" alt="badge rfid"&gt; Badge&lt;/button&gt;
  
  &lt;button role="tab" aria-selected="false" aria-controls="v-pills-settings" id="v-pills-settings-tab" class="nav-link" data-toggle="pill" href="#v-pills-manutenzione"&gt;&lt;img src="./images/come-funziona/iconManutenzione.png" width="60" alt="manutenzione mezzi"&gt; Manutenzione&lt;/button&gt;
  
  &lt;button role="tab" aria-selected="false" aria-controls="v-pills-reports" id="v-pills-report-tab" class="nav-link" data-toggle="pill" href="#v-pills-report"&gt;&lt;img src="./images/come-funziona/iconReport.png" width="60" alt="report attività mezzi"&gt; Report&lt;/button&gt;
  </code></pre>
  
  <p>How can I solve it?</p>
