Subject: Add integration test for split view activation and tab title update
 after renaming a folder

In a split-view tab, the child folder is opened in the left view and other tabs, while the parent folder is opened in the right view. After renaming the child folder from the right view:
- The activated view should not switch to the left view.
- All tab titles should be updated.
