is this a set or array? do we need to worry about duplicates being added?

we could save some code if we did

if (rendererNeedsDeferredUpdate(*renderer)) {
       m_deferredRecomputeIsIgnoredList.add(element);
else
   recomputeIsIgnored(renderer);

> +    if (AXObjectCache* cache = document().existingAXObjectCache())

are you sure you want to lose the accessibilityEnabled() check?

It's a set. Dupes are fine.

I don't mind doing that but in WebCore we prefer early returns (unless it has changed).

Not sure how much that helps and if you look at all the call sites, they don't really check for that (not even the hot ones).
