  1. Open this test case:
    data:text/html,<a href="https://mozilla.org/" aria-describedby="icon"><img id="icon" aria-hidden="true" alt="PDF" src="https://via.placeholder.com/10x10.png">Document</a>
  2. Right click the link and choose Inspect Accessibility Properties.
  3. Check the description property.
    • Expected: "PDF"
    • Actual: ""

ARIA allows hidden elements to be targets of aria-labelledby/aria-describedby. We support this for text content inside hidden elements. However, we don't consider the alt or aria-label attributes.

This is probably going to require explicit code for each attribute, as hidden elements aren't in the a11y tree.
