What issue are you seeing?

I'm trying to ask Codex for a diff of proposed changes... but for viewing changed hunks, it doesn't render deletions as red while additions does render in green highlights.

It does not look good for reviewing changes to the code when it involves deletions.

What steps can reproduce the bug?

Ask to generate a diff for proposed changed (e.g. move the chunk of code to another file or delete portion of code)

What is the expected behavior?

It should highlight in red or other distinct color
