[BUG] Claude Desktop — Collapsed Sidebar

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

When I collapse the sidebar and select an option among Chat, Cowork, and Code, I'm no longer able to switch between them. I need to expand the sidebar again to choose a different option.

What Should Happen?

Switching between Chat, Cowork, and Code should remain possible even when the sidebar is collapsed. The selected option should update immediately upon interaction, without requiring the user to expand the sidebar first.
