I wonder if browsers optimize this search. Rather than using the traditional query by searching through every dom node and check if tag is iframe, which could be slow, maybe the browser holds a reference to all browsing contexts/embeds and returns that. Therefore the amount dom nodes is no longer a factor because it's just ignored.
