My computer displays the tour messages like this (don't mind the bad placement): 
Obviously, the next and back should be switched. It might be good to give up on button roles and other similar things and just use layouts.

Comments
Same on macOS. Luckily searched in time to stop myself submitting a duplicate issue.
I saw this issue right after merging the GSoC project. I played with ok/apply roles in this dialog, but I gave up.
