Worked on the emilk/egui repository to address layout stability issues in horizontal wrapping layouts, specifically targeting multiline text editing scenarios. Focused on resolving a row-height regression by correcting height calculations within the layout logic, which improved visual consistency and reduced glitches during multiline edits. Enhanced the reliability of the editing experience by expanding test coverage, including the addition of regression tests and a canonical test image to validate horizontal_wrapped_multiline_row_height behavior. Utilized Rust for both UI development and testing, ensuring that future regressions are less likely and that the maintainability of layout-related code in egui remains strong.
