Degredation in assigning team members on boards view

Summary

I have a private repository with a small number of team members. Making a new task from the board view opens a sidebar. Previously, from this sidebar I was able to directly assign team members to tasks. Currently, that functionality is bugged and only shows myself. However, by typing in the search field for a team member, it brings up every GitLab user account. If I type in the exact usernames of my team members I am able to assign tasks to them, but it feels as if this is a workaround and unintended.

Steps to reproduce

1. Have a project with team members added
2. Go to the boards view
3. Create a task in a column
4. Focus on the task in the boards view to open the sidebar
5. From the sidebar, attempt to change the assignee of the task
6. Bug manifests itself as team members are not focused

What is the current bug behavior?

In the sidebar, team members are not shown and searching for a member to assign a task to searches the entirety of GitLab.

What is the expected correct behavior?

The sidebar scope should be limited to your team members on private repositories. Searching for assignees should bring up only your team members.
