Contributed to the libgdx/libgdx repository by delivering a feature that enhanced text input reliability in the TextField and TextArea components. Focused on improving undo and redo functionality, the work introduced a new undo method, ensured that undo and redo actions triggered appropriate events, and preserved cursor stability during text operations. Addressed edge cases such as cursor drift and event cancellation, while also updating and expanding end-to-end tests to validate these changes. Leveraged Java and UI development skills, with an emphasis on robust testing practices, to strengthen maintainability and reduce the risk of text input issues in downstream projects.
