Worked on stabilizing the Yoga layout engine within the facebook/react-native repository by addressing a crash related to display:none elements. Using C++ and JavaScript, the developer refined the handling of the hasNewLayout flag so it is updated only during actual layout passes, preventing assertion failures from stale flags. The solution included creating a dedicated reproduction repository to validate the crash scenario and performing end-to-end testing to ensure reliability. Documentation was updated with clear release notes and changelog entries. This work reduced the crash surface for hidden views, improving UI stability for React Native applications with dynamic visibility changes.
