Eric,

This has come up before.  Unfortunately, lots of web APIs assume that 
they're in an iframe tree that chains up in a sensible way to an actual 
browser window/tab, both in terms of implementations and specifications. 
  When browsers tried to not tear down documents when an iframe is 
removed from the tree, they ran into a whole bunch of security issues 
popping up all over the place as a result....

Hence the current browser behavior, which is in fact codified in the 
spec at the moment, since it's the behavior all the browsers agreed on.
