Accessibility: screen reader focus jumps to the top while Codex is generating output

Summary

I am reporting a serious accessibility issue affecting screen reader users in Codex.

When I write a prompt and send it, then try to read the model output while it is being generated, the interface repeatedly moves my screen reader/reading position back to the very beginning of the conversation.

This makes it extremely difficult to follow the latest generated output, because I have to keep navigating back down to the end of the conversation again and again.

Steps to reproduce

1. Open Codex.
2. Use a screen reader.
3. Write a prompt and submit it.
4. While Codex is generating the response, try to read/follow the latest output in the conversation.
5. Press the button/control that should jump to the latest message or bottom of the conversation.

Actual behavior

• The reading position/focus is repeatedly moved back to the top or beginning of the conversation.
• The latest output becomes difficult to follow while it is being generated.
• The jump-to-latest or scroll-to-bottom control does not keep the user at the latest output reliably.
• This creates a very frustrating experience for screen reader users.

Expected behavior

• Screen reader focus/reading position should not be reset to the top while Codex is generating output.
• The user should be able to stay near the latest generated output.
• The jump-to-latest or scroll-to-bottom control should work reliably with keyboard and screen readers.
• New generated content should remain reachable/readable without stealing focus or resetting the reading position.

Impact

This is a major accessibility issue because it prevents screen reader users from reliably reading and following active Codex output as it is generated.

Environment

I can provide more details if needed, but the main issue is reproducible while using Codex with a screen reader and trying to read the generated output in real time.
