Walkthrough

This pull request refactors the code by removing the supportsCSSTransform check from the conditional statement in the html.ts file. This change simplifies the condition by only checking if offsetX and offsetY are not nil. Additionally, the version number in version.ts is incremented from 5.0.38 to 5.0.39. Minor updates are also made to package.json files across different packages.
