Looking more into this Firefox takes a more heuristic approach to
figuring this out (was there a referrer and what is the request type)
and if that approach works out for WebKit it wouldn't require any
port-specific changes. Chromium itself does just ask the `ui` layer what
type of "transition" caused the request which is more in-line with the
spec.
