[Bug] Cmd+Enter to approve permission also sends in-progress message text

Summary

When a permission request appears while the user is actively typing a new message in Claude Code Desktop, pressing Cmd+Enter to approve the permission also submits the partially-typed message text. The sent message cannot be retracted, creating unintended instructions to the agent.

Steps to Reproduce

1. Start a session in Claude Code Desktop (macOS).
2. While the agent is running, begin typing a new message in the input box.
3. Before finishing the message, a permission prompt appears (e.g. asking to approve a file write or bash command).
4. Press Cmd+Enter to approve the permission prompt.
5. Observe: The permission is approved AND the partial/unfinished message in the input box is submitted to the agent.

Expected Behavior

Pressing Cmd+Enter should approve the permission prompt only. The message being composed in the input box should remain unsent and editable.

Actual Behavior

Cmd+Enter both approves the permission prompt AND sends the in-progress message text. The user has no opportunity to retract the sent message, and the agent receives unintended/incomplete instructions.

Root Cause (suspected)

This appears to be a race condition / input focus issue. When the permission prompt appears, it captures the Cmd+Enter keypress for approval, but the keypress also propagates to (or is simultaneously received by) the message input field, triggering submission.

Environment

• Platform: macOS
• App: Claude Code Desktop (standalone, not VS Code extension)
• Reproducible: Yes, when a permission prompt appears while text is already in the input box

Impact

• Agent receives partial/unintended instructions it cannot be told to ignore mid-run
• User cannot retract or cancel the submitted message
• Particularly disruptive in long sessions where the user is preparing follow-up instructions while the agent is still working
