Apr 1, 2025April 2025: Delivered cross-window and iframe CSS style sheet tracking improvements for microsoft/clarity, introducing proxyStyleRules for cross-context manipulation. The refactor enhances tracking accuracy and compatibility while consolidating style shimming improvements across contexts. Implemented robust requestIdleCallback polyfill handling to avoid null yields, with a valid fallback value and a corresponding version bump of the clarity-js package. These changes reduce runtime errors in dynamic iframe scenarios and improve reliability of CSS operations across multiple contexts. Key accomplishments include: (1) cross-window/iframe CSS tracking improvements with proxyStyleRules, (2) refactor to improve tracking accuracy and compatibility and consolidate shims, (3) robust polyfill handling for requestIdleCallback with safe fallback and version update, (4) explicit version bump to reflect dynamic CSS improvements.
