Double rendering after Edit/Resume: history block appears twice

What version of Codex is running?

codex-cli 0.27.0

Which model were you using?

gpt-5

What platform is your computer?

Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

1. Start codex, type "hi" and press Enter; wait for the agent’s reply
2. Press Esc twice to open the transcript (history) selection overlay
3. Press Enter to confirm; immediately after that, the history renders twice (reproducible every time)

What is the expected behavior?

The screen redraws once with no duplicated content

What do you see instead?

The history area is rendered twice; the initial ">_ You are using OpenAI Codex in …" history block appears two times right after confirming from the overlay. This reproduces every time.
