Steps to Reproduce

Please refer to https://github.com/anthropics/claude-code/issues/57139 for context. I added a comment to 57139 however it has not been picked up so I am creating this new issue.

The fix in v2.1.141 successfully resolved this for standard text prompts, however the bug is still present when using slash commands.

• I am now on Claude Code 2.1.160
• OS: macOS
• Terminal: Warp
• Claude Code CLI
• I note this fix was released with 2.1.141
• My relevant keybindings are as below;

    {
      "context": "Chat",
      "bindings": {
        "ctrl+enter": "chat:submit",
        "enter": "chat:newline",
       }
    },

• Note that ctrl+enter does now correctly work for sending text prompts.
• Pressing enter does correctly create a new line in the input window.

What's Wrong

• Bringing up a slash command then pressing ctrl+enter does not send the slash command.

What Should Happen
