Codepen example: https://codepen.io/achint-singh/pen/rNKxVed

Codepen places code within an iframe. In this example, if you view this outside of an iframe (for example, in debug mode)--you will notice a similar issue to Scenario 3 mentioned. There is another bug where aria-activedescendant is broken in an iframe, so this example should be viewed outside of an iframe to view the issue.

Steps to reproduce:
1. Turn on VO in the example.
2. Click the button using enter key, and navigate through the list using the down arrow key.

Notice that once you go past the selected item, (in this case, Option C), the dropdown selector stops moving in sync with the VO focus ring. The VO focus ring remains on option C, while the dropdown selector keeps moving forward. If you keep pressing the down arrow to reach Option A, the VO focus ring and the dropdown selector will sync up again.

The expected behavior is that using the down arrow key should simultaneously move the VO focus ring as well as the dropdown selector and read the options.

----

Tested in: Monterey + Safari Technology Preview (16.4). 

This also does not work in Duck Duck Go + VO.

It works in Chrome + VO.
