In the mobile diff, a click on the user name usually leads to their mobile user page, where one finds a link to their contributions. For users without a user page (aka red link), however, the mobile website launches into the editor instead of displaying the user page. Going back a step in the browser returns to the diff.
As far as I can see, for these user accounts there is no way to reach the user contributions by clicking a link. Instead, one has to manually go to the Special:Contributions URL.
- Visit https://en.m.wikipedia.beta.wmflabs.org/wiki/Special:MobileDiff/349080
- Click user name
- Click contributions
Actual: User cannot navigate to contributions
- The user on a diff page should link to the user page in view mode NOT edit mode
Follow the replication steps. The editor should not load when the username is clicked on.
IT may help to compare this behaviour to https://en.m.wikipedia.org/wiki/Special:MobileDiff/349080 to understand how this worked before.
