## Summary by CodeRabbit

* **Tests**
  * Added a new end-to-end test to verify that search bar filters ("With Attachments", "Last 7 Days", "Starred Emails") can be applied and cleared using the command palette. The test also checks for the correct display and removal of the "Clear" button in the search bar.
