Fails to Switch to Tab in Collapsed Group After Closing Duplicate

[kunaljaykam]

Summary:
The 'TabMirror' Chrome extension is not switching focus to an existing tab in a collapsed tab group after closing its duplicate.

Steps to Reproduce:

1. Create a tab group in Chrome and collapse it.
2. Open a tab with a specific URL outside this group.
3. Open another tab with the same URL and place it inside the collapsed group.
4. Use the extension to identify and close the duplicate tab outside the group.
5. Observe the behavior of the browser.

Expected Result:
The browser should expand the collapsed group and switch focus to the existing tab within that group after the duplicate tab outside the group is closed.
