It's called under FrameLoader::clear(bool) and on a document leaving the frame
(regardless of whether it's headed to the b/f cache or not. The reason the
crash doesn't happen with pages that don't go into the b/f cache is that their
detach() resets the focused node (and doesn't even dispatch blur events)).
