Inter-tutorial links don't work

[naattxx]

Note

I believe it is an old issue

In the tutorial there are 2 internal links to the sections #jumping & #addressing. In the original web version it works fine, but in the Gnome app they throw:

(eu.jumplink.Learn6502:2): Gtk-WARNING **: Failed to launch handler: #jumping is not a valid uri: URI ‘#jumping’ is not an absolute URI
and
(eu.jumplink.Learn6502:2): Gtk-WARNING **: Failed to launch handler: #addressing is not a valid uri: URI ‘#addressing’ is not an absolute URI
