## Summary by CodeRabbit

* **Bug Fixes**
* Fixed floating toolbar remaining visible after deleting multiple
documents via the confirmation dialog so it reliably closes when
deletion completes.

* **Tests**
* Added end-to-end checks to verify the floating toolbar is dismissed
after multi-item and “select all” deletions.
