Shows the wrong diff when asking for approval

What version of the VS Code extension are you using?

0.4.0

Which IDE are you using?

VS Code

What platform is your computer?

Windows

What steps can reproduce the bug?

1. ask Codex to modify at least two things in the repo
2. Codex will show the first diff to approve correctly, approve this diff
3. then Codex will show the first diff again to approve it

What is the expected behavior?

Codex should show the second diff, when asking for approval of the second diff

What do you see instead?

Codex shows again the first diff for the second time. When I approve this diff then actually it is the second diff (which it did not show) that I approve, not the first one. So I approved the second diff without ever seeing the second diff.
This is always reproducible.
I expect Codex to show the correct diff that I'm approving.
