Pull Request Overview

This PR ports changes from the referenced TypeScript pull request by updating the logic for marking JSX factory references in fragments while simultaneously removing obsolete error baselines.

• Updated error baseline files to remove expectations for the unused 'element' error.
• Modified the JSX fragment reference marking logic to use the result of getJsxFactoryEntity instead of the prior local namespace.
