Invalid ARIA role
What it means
These pages use a role that ARIA does not define. An unrecognised role is ignored outright, so the element falls back to its native semantics or, on a <div>, to none at all.
How to fix it
Correct the spelling against the ARIA role list. The usual culprits are invented names like role="clickable" and near misses like role="buton". Better still, use the element that already has the semantics: a <button> needs no role.
