Changed line numbers are not vertically aligned (in chat window, while edits are performed)

What version of the Codex App are you using (From “About Codex” dialog)?

latest

What subscription do you have?

Edu

What platform is your computer?

Windows 11

What issue are you seeing?

When edits are being made to files, and the line numbers change in real time (but also when done), the digits are not vertically aligned. See screenshot:

Both, the 0, and the 2 are too high (or the 7 and the 9 are too low, or both).

This seems to be a regression introduced recently.

My observation is that this is mostly noticeable when having numbers with at least two digits. And potentially, this is also only happening with certain digits (like 2, ...).

What steps can reproduce the bug?

Just have Codex modify some file.

What is the expected behavior?

Correct alignment of digits.

Additional information

Unfortunately, the Codex app code is not open source. Else, one could probably pinpoint the code region where this happens rather quickly.

It is also a bit astonishing that such simple mistakes are not caught (I remember another one where there was always some space missing between terms, or translation errors). But I guess that is the price for move fast; and these are also mostly visual issues, luckily. Still lets me question the QA of the product a bit...
