Summary

Reduced scroll stickiness for Copilot and Chat messages to improve user control and ensure consistent behavior across all message scrolling interactions. The default stickinessThreshold was updated from 100 to 30, and Copilot now uses this unified default.

Type of Change

  • Bug fix
  • New feature
  • Breaking change
  • Documentation
  • Other: Improvement

Testing

Manually verified by observing scroll behavior in both Copilot and Chat panels. Reviewers should focus on confirming the new scroll stickiness feels appropriate and consistent when new messages arrive while the user is scrolling.

  • Self-reviewed my changes
  • Tests added/updated and passing

Reduce copilot scroll stickiness for consistent, less-sticky behavior
ccb15da 
- Changed default stickinessThreshold from 100 to 30 in use-scroll-management.ts
- Removed explicit stickinessThreshold override (40) from copilot.tsx
- Both copilot and chat now use the same default value of 30
- This makes scrolling less sticky across all copilot message interactions
