Multi-select widgets are too big

[nijel]

Describe the issue

The multi-select widgets seem to be sized based on the screen size and number of items. This is especially annoying with large screens and selects that render on few lines.

I already tried

• I've read and searched the documentation.
• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

1. Go to /manage/teams/
2. Click on any team
3. See the selection taking the whole screen while there are just few lines of items to select

Expected behavior

• The widget should not take more space than needed for currently shown items.
• It might scroll if there is too many items to show.
• We should revisit whether there isn't some better implementation of this functionality. The currently used multi.js hasn't received updates since 2021.

Additional context

This probably exists since #12426, but I've only noticed it now with a larger screen 😄
