## Summary by CodeRabbit

- **New Features**
  - Added support for dynamically scaling the height of embedded synced document blocks, including proper handling when folding and unfolding.
  - Introduced a new property to track the scaled height of folded synced document blocks.

- **Bug Fixes**
  - Improved accuracy of height calculations for synced document blocks by accounting for both viewport zoom and block scale.

- **Tests**
  - Enhanced end-to-end tests to consistently apply scaling before running size adjustment checks.
  - Added a utility function to simulate scaling elements with keyboard shortcuts during test execution.
