Steps to reproduce
- Go to a talk page with topic containers enabled using the Timeless skin. E.g. https://www.mediawiki.org/wiki/Talk:Talk_pages_project/Usability?useskin=timeless
- Notice that the ==second-level headings== have two lines, both above and below.
- Notice that the ==second-level headings== have only one line, either above or below.
Since Timeless is not officially supported by DiscussionTools, feel free to decline this task if it would require too much effort, but I hope it wouldn’t. 🙂
