Test case

When using vo+right to select a button which shows/hides some content (by changing display setting and aria-hidden property). If the container has more than around 50 elements, it is impossible to vo+right to the newly shown element.

If you remove some of the numbered <p> tags, the issue goes away.

Test case attached.
