## Summary by CodeRabbit

- **Bug Fixes**
  - Improved focus behavior when switching between tabs to prevent unwanted automatic focusing of the content-editable area.
  - Enhanced selection clearing to avoid unnecessary blurring when the main editable element is already focused.
  - Refined focus checks in tests to specifically target contenteditable elements, ensuring more accurate validation of focus behavior.
  - Adjusted test assertions for block selection to be less strict and removed redundant blur operations for smoother test execution.
  - Updated toolbar dropdown closing method to use keyboard interaction for better reliability.
- **New Features**
  - Added a recoverable property to selection types, improving selection state management and recovery.
