I intentionally chose not to address this in my patch (though perhaps 
that's not the right call).

They throw away any history after the page you clicked the link on 
(which I think is what you mean by the above).

Another option might be, "If you're at a historical page and you click a 
link, add that page as a duplicate to the end of the history." That 
would partially restore the old behavior, but only in this case where 
things might otherwise be confusing.

We could also add a user option to select between these behaviors, since 
the former is the de facto standard for browsers.

(I think the real fix would be something like a history *tree*, but 
that's probably quite a bit more work.)
