研究方向
Start by examining the compare screen component in the Lighthouse CI server code (likely in the 'server' directory). Look for how metrics are filtered or displayed, especially around CLS. Review the logic that determines which metrics show up in the comparison view. Check if CLS is being ignored due to a missing case or a bug in metric key handling. Also, read through the issue comments for any hints or partial solutions.
