What this test checks
This test checks whether form fields in a PDF document are focusable and navigable via keyboard in logical order, and expose correct interactive roles. This test is applicable only if the PDF document contain an interactive form.
Why this maybe a barrier
Users relying on keyboard navigation or assistive technology cannot interact with the form if fields are not tabbable or focusable, preventing form completion. This can be an accessibility barrier for users, specifically visually challenged users trying to navigate and interact with PDF forms using the keyboard.
