Multiple assignee widget should update when changes are made by other users
Summary
The multiple assignee widget doesn't reflect changes made to assignee after the page has loaded.
This can lead to users accidentally reassigning people who had unassigned themselves!
Steps to reproduce
- Create an issue and assign two users to it
- Have both users view the issue, seeing both users as assignees
- Have one user unassign themselves from the issue
- Without reloading the page, have the second user unassign themselves from the issue
- The first user will have become re-assigned
What is the expected correct behavior?
The assignee widget should reflect changes made to assignees that happen after the page load.
