Thanks for doing this.

I guess the main project had "use unique domain" setting on

No it doesn't, see attached. I think this confirms what we thought on the parent issue. When a non-maintainer runs the job, the url has both the issue number -3531742 and the extra digits -98ccf5, even if the 'unique domain' is not ticked.

I will push a change to this MR too, and I expect it will generate the real doc site, without the issue number or digits. Then we can repeat with the 'unique domain' ticked and get both results from that scenario.

Wrote to http://project.pages.drupalcode.org/gitlab_templates_downstream which is the real site, as expected.

Now ticking the 'unique domain' and run as maintainer
