## Summary by CodeRabbit

- **New Features**
  - Improved rendering performance and consistency for widgets within frames.
  - Frame titles are now directly associated with individual frames and are draggable.

- **Bug Fixes**
  - Selection logic for frames has been refined to better handle locked states and title area interactions.

- **Refactor**
  - Frame title widget and related components have been simplified for clarity and maintainability.
  - Removed dynamic positioning and click toggling from frame titles for a cleaner interaction model.

- **Tests**
  - Added a test to verify that frame titles are draggable.
  - Temporarily disabled tests related to frame title stacking and selection due to ongoing changes.
