Unfortunately I've just found out that this isn't working entirely correct; my apologies for accidentally breaking this in PR 8775. Compare e.g. this link: http://mirrors.ctan.org/info/lshort/english/lshort.pdf#page.157, with this one: http://mirrors.ctan.org/info/lshort/english/lshort.pdf#nameddest=page.157. Notice how in the *second* case, the history stops working correctly. *The various edge-case regressions in the new `PDFHistory` code is reminding my why I put off the rewrite for so long :-(*
