What issue are you seeing?

When a prompt is processing, including when input is requested from the user, I can scroll up with scroll wheel or pgup, but the CLI app brings the screen to the bottom of the CLI history after about 200ms.

What steps can reproduce the bug?

Set Permissions to strict, launch a prompt, try to scroll up.

What is the expected behavior?

When the response of the agent is longer than the screen allows, and only the last part of the agent response is shown, and the user uses the scrollbar, scrollwheel, or pgup keys to scroll upwards, then the app should allow that and not bring the focus back to the latest messages, either during text generation or (even more so) when text generation is paused due to asking for user input.

Additional information

Distinct from #23280 as I'm not asking for an additional Codex feature, this is about native Terminal/OS functions being blocked from working by Codex functionality.

If I understand correctly, this scroll down feature was implemented as a hack to fix other bugs where the conversation wasn't scrolling to the bottom for other users, but I may be wrong.
