During June 2025, Alberto Botella enhanced line-clamp rendering in the mozilla/gecko-dev repository, focusing on improving how ellipsis is placed and balanced when used with text-wrap: pretty. He addressed rendering correctness by accounting for ellipsis width during text balancing, which reduced visual glitches and improved UI consistency. Using CSS and HTML, Alberto expanded Web Platform Tests to cover edge cases, validating stability and preventing crashes in scenarios involving line-clamp and text-wrap: balance. His work increased cross-compatibility and aligned implementation with design specifications, resulting in more robust front-end behavior and faster regression detection through targeted test improvements.
