Codex Desktop macOS: Copy button opens right-side panel instead of copying

Summary

In Codex Desktop on macOS, clicking the copy button in the conversation UI triggers the right-side panel/popover instead of copying the content. Because the panel opens over or near the copy target, I cannot reliably click Copy.

Environment

• App: Codex Desktop for macOS
• Codex version: 26.429.30905 (2345)
• macOS version: [fill from About This Mac]
• Hardware: [Apple Silicon / Intel, model if known]
• Subscription: [Plus / Pro / Team / Enterprise]

Steps to reproduce

1. Open Codex Desktop on macOS.
2. Open any existing thread with an assistant response or code block.
3. Move the cursor to the copy button.
4. Click the copy button.

Expected behavior

Clicking the copy button should copy the target content to the clipboard without opening any unrelated side panel.

Actual behavior

Clicking the copy button opens the right-side panel/popover. This intercepts or blocks the intended copy action, so the content is not copied reliably.

Impact

This makes copying code snippets or assistant responses from Codex Desktop difficult or impossible in normal use.

Notes

This appears to be a UI hit-target / z-index / click-handling issue. The copy button and the right-side panel trigger seem to overlap or conflict.

Attachments

I can provide a short screen recording showing the click target and the panel opening.
