Greptile Overview

Greptile Summary

This PR fixes styling bugs in the trace span timeline visualization. The changes refactor hover interaction handling and correct visual issues with the timeline elements.

Key improvements:

• Fixed timeline overflow from overflow-visible to overflow-hidden to prevent hover line from extending beyond timeline bounds
• Refactored hover tracking from global window listener to component-scoped callbacks, improving performance and reducing unnecessary re-renders
• Improved hover tooltip positioning by moving it outside the scrollable container and tracking Y-axis position
• Fixed hover line styling to use inset-y-0 instead of negative margins for proper containment
• Simplified prop interface by replacing hoveredPercent, hoveredWorkflowMs, and forwardHover with cleaner onTimelineHover and onTimelineLeave callbacks
• Enhanced tooltip styling with border and shadow-lg for better visibility

Confidence Score: 5/5

• This PR is safe to merge with no risk - purely cosmetic styling fixes with improved architecture
• The changes are well-structured refactoring that improves code quality and fixes visual bugs. The modifications are isolated to timeline hover interactions, use proper React patterns (local state and callbacks), and maintain backward compatibility with the component API
• No files require special attention
