- As a non-logged user on arwiki on a random article page click 'Create account' and go through the account creation steps - the page with Welcome survey will be displayed.
- Click on any option on Special:WelcomeSurvey page ('Skip survey', a username link or select any answers) - a user will be re-directed to Special:UserLogin and is logged out
Seems to happen fairly frequently on arwiki, maybe because of some site script changing what requests are made during signup. Possibly caused by T299193: MediaWiki login failure due to race condition with session cookie. T313064: WelcomeSurvey: Post-login redirect hooks might interfere with central login during signup might contribute to the impact.
