### What happened? There is a constant visible white border in the trace spans in the TraceDiff comparison view. This appears to be a CSS styling issue. ### Steps to reproduce 1. Go to a trace comparison page 2. Look at the spans representing "more" operations 3. Notice the white border in the trace spans ### Expected behavior There should be no empty borders in the trace spans ### Relevant log output ```shell ``` ### Screenshot <img width="1875" height="909" alt="Image" src="https://github.com/user-attachments/assets/2d4fd986-7cbe-4ee3-a673-ed4a734ae126" /> <img width="447" height="236" alt="Image" src="https://github.com/user-attachments/assets/1c92ceaa-3b70-4ec9-87fe-d20cc755fb9b" /> https://github.com/user-attachments/assets/c55bbdb8-1084-4ff5-8ff6-03ae618848f6 ### Additional context _No response_ ### Jaeger backend version _No response_ ### SDK _No response_ ### Pipeline _No response_ ### Stogage backend _No response_ ### Operating system _No response_ ### Deployment model _No response_ ### Deployment configs ```shell ```
