Issue: Users who have been removed from the KB still appear in the article accessibility selector if they were previously set as accessors. This creates confusion, especially when multiple users with similar names exist. Expected Behavior: Users removed from the KB should no longer appear in the article accessibility selector. Alternatively, consider an indication (e.g., a label or strikethrough) that the user is no longer in the KB. Steps to Reproduce: Assign a user as an article accessor. Remove the user from the KB. Open the article accessibility selector. The removed user still appears as one of the accessors. Proposed Solution: Automatically remove users from the article accessibility list when they are removed from the KB. OR add a label indicating that the user is no longer active. Consider the impact of removing accessors if a user is later re-added to the KB.
