And an example from MDN on how it should look:

<ul role="tablist">
  <li role="presentation">
    <a role="tab" href="#">Tab 1</a>
  </li>
  <li role="presentation">
    <a role="tab" href="#">Tab 2</a>
  </li>
  <li role="presentation">
    <a role="tab" href="#">Tab 3</a>
  </li>
</ul>

@matthewcn56 are you explicitly handling these issues or do you want me to? Very down for Alireza to take it on if he's interested!
