According to 'https://www.w3.org/TR/wai-aria-1.1/#aria-setsize', 'aria-setsize' defines the number of item in a set. This is very common for virtualization because not all DOM element is presented. VoiceOver does not respect 'aria-setsize' when narrates a list. Here's a simple HTML for reproduce: <h2 id="label_fruit">Available Fruit</h2> <ul aria-labelledby="label_fruit"> <li style="list-style-type: none;" aria-setsize="16" aria-posinset="5"> apples </li> <li style="list-style-type: none;" aria-setsize="16" aria-posinset="6"> bananas </li> <li style="list-style-type: none;" aria-setsize="16" aria-posinset="7"> cantaloupes </li> <li style="list-style-type: none;" aria-setsize="16" aria-posinset="8"> dates </li> </ul>
