Updated after DiscussionTools mobile deployment
Steps to replicate the issue (include links if applicable):
- Go to https://test.m.wikipedia.org/wiki/User_talk:Stjn
- Try clicking Welcome to Wikipedia, stjn! section
- See that it has an Edit link that just opens/closes the section
This bug prevents me from using <h2> in future version of welcome template in Russian Wikipedia. I want to make it accessible to mobile users, but it seems like the mobile sections only work if you mark up the section with == … ==. That causes another issue for desktop users, since it makes the section display an  link that would confuse new users because it goes to a (full-protected) template.
The ideal solution for my use case would be to show the zero section to mobile users, but I’m not sure if that is even in the plans, so at least this bug needs to be fixed so I can provide a good enough experience both on desktop and mobile. (Right now I am considering to hide the edit link with TemplateStyles, but that might possibly open its own can of worms if <templatestyles> would be before the heading.)
