Misspelled ARIA attributes
aria-valid-attr
Some attributes start with aria- but are not real ones. Usually a typo, and they do nothing at all.
Who this affects
Screen reader users, who silently lose whatever the author meant to convey.
Fix it in WordPress
Check hand-written markup in Custom HTML blocks and theme templates.
What the fix is, technically
Correct the spelling against the ARIA specification, or remove the attribute.
