Cannot move project into group

Summary

I am trying to move a project from Master into a group, and so far have not been able to.

Steps to reproduce

In our project, we originally created to repos, which are displayed in the dropdown at top left of screen (to the right of the hamburger menu) like this:

• Master / project-1
• Master / project-2 (not the real names)

Subsequently we discovered Gitlab groups, which seem to be a great way of organising a software project that spans multiple repositories.

So we created a group (group-name for the purposes of this Issue), and added the two existing repos (Gitlab projects) to it.

We then created a new repo/project (project-3) from within the group. The dropdown at top left of screen now looks like this:

• group-name / project-3
• Master / project-1
• Master / project-2

Expected behavior

When editing a project, I would expect to see an option to move it to a group.

Actual behavior

There is no option that I can see to allow me to move a project into a group.
