Comment 1 for bug 1700004

I cannot replicate this, clicking any link in a book, including a
footnote link, takes me to the page of the link and clicking back,
either in the viewer controls or the browser back button, takes me back
to the original page (or in a few rare cases the page before it).

The only caveat is that if you click back immediately after clicking the
link it wont work (you have to wait approx. a second).

Tested in Chrome and Firefox.
