You are not supposed to edit the ini manually. You could have just used ./mach update-wpt https://github.com/servo/servo/actions/runs/24202318107

Removes the `#[cfg(feature = "gecko")]` gate on `TextAlign::MatchParent` in `style/values/specified/text.rs`, enabling `text-align: match-parent` for Servo. The computation logic (resolving `start`/`end` to physical directions based on parent writing mode) was already correct and needed no changes.
