[App] Popout Window run-location click hides the window and breaks the hotkey until restart; cloud projects cannot start new chats from the desktop app

What issue are you seeing?

Two reproducible issues in the Codex App desktop UI:

1. Popout Window run-location control hides the window and kills the hotkey until restart. After enabling the experimental Popout Window with a global hotkey (Alt+3), clicking the run-location label (“电脑” / Local) at the top-left of the popout makes the window disappear. Pressing the hotkey again does not reopen it; the only recovery is restarting the ChatGPT desktop app, and the bug recurs every time.

2. Cloud projects cannot start new chats from the desktop app. A cloud project synced from Codex Cloud (GitHub repository + environment created on the web) appears in the sidebar with its cloud task, but the project row has no “New chat” action; the compose (“编写”) button next to the project starts a chat bound to a local project instead, and the project picker lists only local projects. Cloud access is enabled in the app state (codexCloudAccess: enabled, environment object registered), so this looks like a missing/blocked UI entry rather than a connection failure.

What steps can reproduce the bug?

Popout Window:

1. Settings → Experimental features → set a global shortcut for “Popout Window” (e.g., Alt+3). Without a hotkey the feature stays off.
2. Press the hotkey to open the popout window.
3. Click the run-location label at the top-left (“电脑” / Local).
4. The popout window hides. Pressing the hotkey again does not bring it back.
5. Restarting the app restores the hotkey; the bug reproduces on every attempt.

Cloud project new chat:

1. On Codex Cloud (web), connect GitHub and create a cloud environment for a repository.
2. In the desktop app, the cloud project appears in the sidebar and its web-created cloud task syncs into it.
3. There is no “New chat” action on the cloud project. Clicking the compose button next to the project creates a chat in a local project. The project picker shows only local projects.

What is the expected behavior?

1. Popout Window: clicking the run-location control should not hide the window, or the hotkey should still toggle it back, without requiring an app restart.
2. Cloud projects: starting a new chat from a synced cloud project should open the composer in cloud mode with the environment selector, consistent with the app’s “Start cloud chats from the composer” behavior.

Additional information

• App state confirms cloud is configured correctly: codexCloudAccess=enabled; environment object registered (label “codex-cloud-test”, description “Codex 云端测试环境”); sidebar cloud group expanded.
• The run-location dropdown strings exist in the app bundle under composer.hotkeyWindow.modeDropdown.* (Local project / Worktree / Cloud), but the selector is only reachable in the experimental Popout Window, which is off by default (“Set a global shortcut for Popout Window. Leave unset to keep it off.”).
• A cloud task created on the web synced correctly to the desktop sidebar, so sync works; only creating new cloud chats from the desktop fails.
• No error message is shown in either case; both are UI behavior issues.

Reproduce both paths in the Windows desktop app: the experimental Popout Window’s run-location control and the cloud project’s sidebar, composer, and project-picker flow. Trace the popout toggle and project-selection entry points, then verify that the popout remains recoverable with its hotkey and that a synced cloud project can start a cloud-mode chat with an environment selector.
