Orca checklist

What to verify

form.html: unnamed native form is not a landmark, named form is a landmark.
input-radio.html: radio controls announce correctly with grouping semantics.
aria-form.html: named role="form" appears as form landmark.
aria-posinset.html: set size and position announcements are stable.
