Documents going into the b/f cache aren't really torn down, detach() doesn't
traverse the tree, so the blur-on-detach didn't use to happen in that case. For
documents not going into the b/f cache, the focused node is reset before the
any child nodes are detached, so again the blur event isn't dispatched.

I think the info might be available e.g. in the form of document()->attached()
being false (despite the node itself being attached).
