Can you hide this behind adoptNode just as we did for "magic iframe"? The
nice thing about adoptNode is that the browser gets told both the source and
destination parent nodes. This way there is never a disconnected state.
So long as we unload when moving between documents, we should be pretty
safe as far as the issues which plagued magic iframe are concerned.
