Pull Request Overview

This PR fixes an issue where interaction was blocked while hovering over the DataGrid header during dragging operations (T1291988). The fix involves caching the bounding rectangles of dragging panels at the start of a drag operation instead of calculating them repeatedly during drag movement, which was causing performance issues and blocking interactions.

Key changes:

• Introduced caching mechanism for dragging panel bounding rectangles to improve performance
• Refactored _pointCreated method signatures to accept an object parameter instead of multiple positional arguments
• Updated all callers to pass cells collection directly instead of just cell count
