The question of "does a detached frame even have a back/forward list to
manipulate?" already has an answer elsewhere in our code - calling
history.length() on a detached frame will return 0 (not even 1!!)

I'm pretty sure an early return is the right way to go here.  If we later
uncover an incompatibility with the spec or the real web, then we can do what's
needed to fix that.
