The Blender foundation uses Gitea to provide the projects.blender.org. This is likely to be a issue in Gitea and should probably be reported to Issues · go-gitea/gitea · GitHub if it hasn’t been made already.
Either way CC @bartvdbraak just so you know about it and in case it is something specific to the Blender verison.
I cross-checked the functionality on our projects.blender.org versus the latest on demo.gitea.com and it seems that the latest upstream version has fixed this issue.
We will soon be updating our instance, resolving the issue.
