Can't share a project with a group I'm not a member of

Summary

We got multiple groups on our GitLab instance. For example we just got some freelancers onboard a project and have a separate group for those. I'm not part of that group, as I'm not a freelancer. I want to share the project with specific permissions with this group.

Steps to reproduce

• Create two groups: A and B
• Join group A
• Create a private project P within group A
• Try to share the project with group B

Expected behavior

I want to be able share the project with group B. Without being a member of group B.

Actual behavior

I'm required to join group B and then I can select the group when sharing project P.
