Selection actions no longer appear for text selected inside Project Preview panel

What version of the Codex App are you using?

Codex Desktop 26.527.31326 (CFBundleVersion 3390)

Bundle identifier: com.openai.codex

What platform is your computer?

What issue are you seeing?

Selection actions no longer appear when selecting text inside the right-side Project Preview / file preview panel.

In the chat transcript, selecting text still shows Codex's contextual selection menu with actions such as:

• Add to conversation
• Ask in side chat

However, when selecting text inside the right-side Project Preview panel, the text is visually selected/highlighted, but the same Codex selection action menu does not appear. As a result, selected preview text cannot be added directly to the conversation from the selection UI.

This used to work previously. The regression appears global: it happens across all projects tested, not just one workspace or one file.

What steps can reproduce the bug?

1. Open Codex Desktop on macOS.
2. Open any project.
3. Open a Markdown or HTML file in the right-side Project Preview / file preview panel.
4. Select some text inside the rendered preview.
5. Observe that the text is highlighted, but no Codex selection action menu appears.
6. Select text in the normal chat transcript.
7. Observe that the Codex selection action menu does appear there.

Actual behavior

Text selection works visually in the Project Preview panel, but the selection is not connected to Codex's contextual selection actions. The action menu shown in the chat transcript does not appear in the preview panel.

Expected behavior

Selecting text inside the Project Preview / file preview panel should show the same Codex selection action affordances as selecting text in the chat transcript, including adding the selected text to the conversation or asking about the selected content in side chat.

Scope

• Reproduces across all projects tested.
• Reproduces with Markdown and HTML preview content.
• Chat transcript selection actions still work.
• The issue appears specific to the right-side Project Preview / file preview surface.

Additional context

This is separate from composer input focus / caret issues. It is specifically about the Project Preview panel no longer exposing Codex's selection action menu for selected preview text.

Screenshots show the contrast clearly: selected text in the Project Preview panel is highlighted with no contextual action menu, while selected text in the chat transcript shows the action menu.
