Cannot enter / render folder with jinja template {{ in the name }} - UI bug

Summary

It is not possible to enter the folder with {{ in the name }} via web UI.

I have a cookiecutter project which uses jinja to template files and folders. If you go to project https://gitlab.com/remak_team/open-source/rmk-pypackage and click on the folder {{cookiecutter.project_slug}} page won't render the underlying structure instead it loads same page but url changes.

This is an example how url is being generated by clicking on {{cookiecutter.project_slug}}
