Assignee Field Update is Frustrating! Issue Tracker

In the past when I create an issue and assign it to a developer I could simply press on the drop down menu, see the list of developers/my team members and click on one to assign the task.

Over the past week some time you guys have rolled out an update that no longer allows me to do this! It now looks like this "Find a user by their name" (seems you may have also added an 'assign to me' option to quickly assign a task to myself which is fine, but the problem is the missing auto list). I am not sure if it's a bug that the list does not default display all members or you guys intentionally made it so I need to start typing a username before the team member will even be suggested (which makes no sense to me at all .. I have to memorise all of my team members usernames?).

After using your service for many years and creating thousands of tasks I find this update to be extremely frustrating - before it used to take me 1-2 seconds just to click that Assign to menu and then directly click again to select who I wanted to assign the task to. Now I need to click on the field and MANUALLY start typing a name because I can see any of my developers! The list is actually empty until I start typing the developer's name! So not only does it take me much longer now because I have to manually start typing just to see the list, I also need to memorise all of my developers usernames otherwise I cannot find them to assign the task to!! Please fix this so we can actually see the list of team members again as default! If you want to have the type and find team members, that's fine, but you need to provide a list of team members as deafult before a user starts typing as well!
