New View's custom User Picker (multiple users) should look like Old Issue View

There are a couple of differences in how multi-user picker behaves on the New Issue View compared with the Old.

In the old view, the list always shows together with the key typed letter. Easier to select a new user.

However, in the new view, the list always shows at the top. It causes problems for selecting a new user once the field gets large, requiring you to zoom or scroll up to select the users:

Another important point that's eye-catching is how the User Picker shows the users already select as well (the Old View is "cleaner"):

Old Issue View:

• Shows the number of additional users.

New Issue View:

• Shows all users, despite the field cupping a huge space.
