Research direction
The bug is a regression introduced between versions 3.8.0 and 3.8.1. Focus on the MultiSelect component's dropdown list and its scroll state management. Examine the `packages/select/src/components/multi select/` directory for changes related to scroll position resetting. Check the git history for commits between those versions that altered the dropdown behavior.
