GitHub file browser should show a link to a submodule whose url in .gitmodules is ./

[WofWca]

In my project I use a submodule that is stored in the same repository, but as a branch (orphan branch, do be precise).
If you open the GitHub file browser, that submodule is shown, but there's no link to its source code.
If I were to explicitly set that submodule's url to this very project's GitHub repo URL (https://github.com/WofWca/jumpcutter.git) instead of ./, it would become a link. See https://github.com/WofWca/jumpcutter/tree/23b14ac633e0cbb7b8e787a06c11678041e4ab5e/src. I think it should work the same way with ./. In GitLab it does work.
