Right now, if you go to the following page and click "Prev", it'll send you

My research indicates that this might caused by a bug in libxml2, but
regardless, a minimal fix is to change the link generation code to use

reverse axes.  Patch attached.

Thanks for the patch.

I tested it and with patch the Prev tab works fine towards 45.6.
