Refs #431297 (closed)

How to set up and validate locally

1. Create a public project in a public group
2. Add a 1+ MiB file to the project repository
3. Set the repository size limit to 1MiB (Admin -> Settings -> General)
4. As the user who created the project, view the group and project - you should see a repository limit banner
5. Login as another user who has not been added to the group/project and view the project - you should see the limit banner
6. Checkout this branch - you should no longer see the limit banner as the non-member user

Numbered steps to set up and validate the change are strongly suggested.
