Codex Desktop Find in task reports No matches for visible thread text

What version of the Codex App are you using (From “About Codex” dialog)?

Codex Desktop on Windows, Microsoft Store/AppX package:

OpenAI.Codex_26.623.19656.0_x64__2p2nqsd0c76g0

What platform is your computer?

Windows, x64.

Microsoft Windows NT 10.0.26200.0
Microsoft Windows 11 Business
OS architecture: 64-bit

What issue are you seeing?

The Codex Desktop in-thread find/search UI can report No matches for text that is visibly rendered in the currently open thread behind the search popover.

In the observed case, a short numeric token was visible in the conversation body, but typing the same token into the Find in task / Ctrl+F search box showed No matches. The visible text was in normal rendered assistant-message content, not hidden behind a collapsed disclosure.

This looks like the in-thread find index/scope is stale or not searching the rendered thread content that is currently visible on screen.

I have a screenshot showing the search box containing the exact token and the same token visible in the thread behind it, but I am not attaching it publicly because the thread text includes private project/work-item context. I can provide a redacted/sanitized screenshot if useful.

What steps can reproduce the bug?

1. Open Codex Desktop on Windows.
2. Open a local Codex thread containing a visible, unique token in the rendered conversation body. In my case this was a short numeric work-item-style token in an assistant response.
3. Press Ctrl+F / open Find in task.
4. Type the exact visible token into the search field.
5. Observe the find popover reports No matches while the same token remains visibly rendered behind the popover in the open thread.

What is the expected behavior?

Find in task should match text that is visibly rendered in the current thread content and allow jumping to that match.

If a subset of rendered content is intentionally excluded from in-thread search, the UI should make that scope clear. Otherwise, visible text in the open thread should be searchable.

Additional information

This appears distinct from broader global/thread-title search feature requests. The failure is in the active-thread find UI: visible text in the open conversation is not matched.

I searched existing openai/codex issues for combinations of No matches, Ctrl+F, Find in task, visible text, and thread search. I found related search/sidebar/title reports, but not this exact active-thread visible-text miss.
