What's Wrong?

Description:
In the Claude Code desktop app, the Enter key does not send the message when typing in the Code tab. Instead, it inserts a new line. The same Enter key correctly sends messages in the Chat and Cowork tabs.

OS: Windows 11
Claude Code desktop app (auto-updates channel: latest)
Model: Sonnet

What Should Happen?

Actual behavior:
Enter inserts a new line. Must click the send button with the mouse to submit.

Things already tried (none worked):

~/.claude/keybindings.json with "enter": "chat:submit" under Chat context
Shift+Tab (chat:cycleMode) to toggle mode
Ctrl+Enter
Alt+Enter
Environment:
