This simplest solution, assuming that you are only going to pages on the
same site, is to use iframe.contentDocument.location.replace() to update
the URL, rather than setting the src attribute.
You can also just remove the <iframe> altogether and insert another one.
At this point I doubt we can really change how iframes work with session
history, there are too many sites that depend on it.
