Indirect project members are missing in issue filter autocompletion

Summary

When filtering issues and using author or assignee filter, only direct project members are shown in autocompletion (even after you type first letters of their name). Previously, there were also users that have access to the project via group share.

Steps to reproduce

  1. Invite group to a project (Project information -> Members -> Invite a group)
  2. Go to issues page (ie. https://gitlab.com/gitlab-org/gitlab/-/issues/)
  3. Click into filter field and choose "Author" or "Assignee" filter and "=" or "!="
  4. In autocompletion helper there will be shown direct members of the project, but not members of group added in step 1

Example Project

https://gitlab.com/apploud-public/bug-example-project/

This project is shared with @apploud-public/test-group which has @MrPalmic as it's member.

What is the current bug behavior?

In https://gitlab.com/apploud-public/bug-example-project/-/issues @MrPalmic is missing in autocompletion (even after you type "mrp" manually).

What is the expected correct behavior?

@MrPalmic should be in the autocompletion.
