Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.88.0
• OS Version: Linux

Steps to Reproduce/verify:

1. Make some changes to several files in a Git repository.
2. Open "Multi-diff" in Source Control view.
3. Stage all files.
4. The "Git: Changes" editor tab won't be closed automatically, leaving with a tab title that contains (0 files). Expected behavior is that the tab should be closed automatically when staged changes or commited changes, as "Single-diff" does.
