Mixed-/Upper-case GitLab spacename makes registry not pick up images in GitLab.

As many of you know you cannot have a docker-image reference with uppercase letters in it.

$ docker tag <someimage> registry.my.gitlab/T4cC0re/project:tag
Error parsing reference: "registry.my.gitlab/T4cC0re/project:tag" is not a valid repository/tag

My username on my own Gitlab-ce 8.8.2 is written in mixed casing T4cC0re. I have a project in my space that i pushed an image for with lower-cased name registry.my.gitlab/t4cc0re/project. However this pushed image is NOT shown in my project's containers.

https://gitlab.my.gitlab/T4cC0re/project/container_registryonly shows me

No images in Container Registry for this project.

I suspect this could be due to the fact that the space is written in lower-case in the docker image, while being mixed-case in GitLab and thus is not picked up.
