problem with the display format in the diff/file editor

current format:

<img width="378" height="292" alt="Image" src="https://github.com/user-attachments/assets/b70d8567-8821-4b0b-ab73-eebc42750cf4" />

should be like:

<img width="280" height="96" alt="Image" src="https://github.com/user-attachments/assets/a304b8fc-83a7-4924-b891-6579a6c5db0d" />
