Alt+Up does not open a queued Codex question on Windows

Alt+Up does not open a queued Codex question on Windows

1. Graphical issue inside a terminal pane

Basic information

zellij --version: zellij 0.45.1

stty size: Unavailable in native Windows PowerShell. The PowerShell window size is 46 188.

ver: Microsoft Windows [Version 10.0.26200.9445]

Further information

Codex CLI 0.154.0 shows a queued question with the gpt-6-astra model.

The prompt tells me to press Alt+Up to answer the question.

Codex does not respond when I press Alt+Up inside the Zellij pane. The question stays queued.

Minimal reproduction

1. Start Windows Terminal.
2. Start PowerShell 7.6.6.
3. Start Zellij.
4. Run Codex with the gpt-6-astra model.
5. Give Codex a prompt that makes it ask a question.
6. Wait for the Queued follow-up inputs message.
7. Press Alt+Up.

Expected behavior

Codex opens the queued question and lets me answer it.

Actual behavior

Alt+Up causes no visible response. Codex keeps the question in the queue.

Screenshot

The screenshot shows one queued question and the alt + ↑ to answer instruction.
