I thought I just suggested that?

Everything works normally (as if it was still attached) until it is
reattached, when the situation is re-evaluated.

In terms of resource consumption, I don't see how this would be any
different to any other kind of leak that web content can trigger. (I think
someone mentioned that iframes can be GC'd normally)
