Codex App: slash command and skill picker selections in side chat do not apply until side chat is closed

Summary

In Codex Desktop, slash command / skill / command / agent selections from the composer picker do not actually get selected while a side chat is open. The selection only starts working again after closing the side chat.

Repro steps

1. Open a main Codex chat.
2. Create/open a side chat and keep it open.
3. In either the main chat or the side chat composer, type /.
4. Click a skill, command, or agent from the picker.
5. Observe whether the clicked item is inserted/selected.
6. Close the side chat.
7. Try the same / picker selection again.

Expected behavior

Clicking a slash picker item should immediately select/insert that skill, command, or agent in the currently focused composer, whether or not a side chat is open.

Actual behavior

While the side chat remains open, clicking picker items appears to do nothing or does not commit the selected item. Closing the side chat makes selection work again.

Notes

This feels like a Codex App composer/focus or overlay routing bug around side chats. The side chat may be capturing or invalidating the picker selection event, or the picker may be applying the selection to the wrong composer state.

Related area: side chat UI/session behavior and slash/skill picker behavior, but I did not find an exact existing issue for this specific selection-not-committed-until-side-chat-closed case.
