"Open in New Tab" pops error: command 'workbench.action.moveEditorToEndOfGroup' not found

Summary

Running Claude Code: Open in New Tab from the command palette pops an error dialog every time:

Command 'Claude Code: Open in New Tab' resulted in an error command 'workbench.action.moveEditorToEndOfGroup' not found

The panel still opens, but the dialog blocks until dismissed.

Reproduce

1. Connect VS Code to a remote host via Remote-SSH.
2. Install the Claude Code extension on the remote (resolves to 2.1.126, darwin-arm64).
3. Run Claude Code: Open in New Tab from the command palette.
4. Error dialog appears.

I do not see this on the same machine when the extension is installed locally — only the Remote-SSH server-side install hits it.

Environment

• VS Code 1.106.x
• Claude Code extension 2.1.126
• macOS Darwin 25.3.0 (darwin-arm64)
