a11y.14: role=combobox, role=listbox and role=option were all present and nothing connected them -- no ids, no aria-controls, no aria-activedescendant -- so arrowing through nineteen options moved a visual highlight and announced nothing. Reproduced on the smart-playlist rule editor against the browser's own computation rather than a snapshot: getFullAXTree reported no activedescendant and no controls on any of the five comboboxes on the page. After, the same node carries both. aria-selected also meant 'highlighted', which is the one thing it does not mean: a user arrowing past an option heard it announced as selected while the value they had chosen was announced as unselected. It is the chosen value now, and the highlight is what activedescendant points at. The IDREF tests assert the link rather than the attribute -- an activedescendant naming an id no element carries is exactly as silent as no attribute, and reads as fixed.
