I think it's actually quite different. Normally, for an element that got
broken into multiple CSS boxes, all the boxes will still have the same
"nearest scrollable ancestor". IFRAMEs don't change this. CSS Regions,
however, can change this so that the boxes might have different "nearest
scrollable ancestors".
