Why?

How would it work? If the port gets disentangled, it means the document  
has to set the salvegeable flag to false, so that navigating back doesn't  
put the document in a broken state. Do browsers do that? Is it the best  
thing to do?

What if another document also has a reference to the port, does it still  
get disentangled when the owner gets navigated?
