Worked on enhancing UI input stability within the godotengine/godot repository, focusing on the LineEdit control. Addressed a critical bug where LineEdit failed to retain text input focus when re-enabled while already UI-focused, ensuring caret visibility and preventing unintended focus drift. Utilized C++ to implement conditional logic in the set_enabled() method, allowing immediate input focus capture for UI-focused controls. Improved user experience by eliminating scenarios where arrow keys could inadvertently shift focus away from LineEdit, thereby reinforcing reliable input handling. Updated documentation and tests to support maintainability and prevent regressions in LineEdit-like components, emphasizing robust UI development practices.
