VS Code extension: renamed session title updates visually but clicking it does not switch/open the expected session

Description

In the Claude Code VS Code extension, renaming a session from the session list appears to update the visible title, but clicking the renamed session does not appear to switch/open the expected session. The previously selected conversation/content remains visible, or the session selection state appears stale.

Steps to reproduce

1. Open VS Code with the Claude Code extension enabled.
2. Open the Claude Code sidebar/session list.
3. Start or keep multiple Claude Code sessions.
4. Rename one session from the session list.
5. Click the renamed session.
6. Observe whether the editor/sidebar switches to the renamed session.

Expected behavior

After renaming a session, clicking the renamed entry should reliably select/open that same session. The visible title, selected item, and opened conversation should stay in sync.

Actual behavior

The visible title changes, but clicking the renamed session does not appear to open/switch to the expected session. The UI appears to keep showing the old or previously selected session.

Environment

• Claude Code VS Code extension version: (unavailable via command line)
• OS: macOS 26.5 (BuildVersion 25F71)

Additional notes

This may be a VS Code extension session-list refresh/cache issue or a session title/index synchronization issue.

I can provide additional diagnostics if needed.
