I am trying to figure out why NVDA isnt speaking the inner HTML of a div that has a tabindex. The snipped below is inside a jquery-ui-dialog with an aria role of dialog. If I remove the aria-label, and I tab to this section NVDA just says "section". If I leave the aria-label, it speaks it. Is there a way to have it say the inner HTML without duplicating the text everywhere?
<div class="current-chapter" tabindex="0" aria-label="Chapter 1 of 10">
Chapter 1 of 10
</div>
