It appears there is an extra closing bracket in the NumericTests method that does not correspond to an opening block. Consider removing this bracket to ensure correct test structure.

- [nitpick] Consider renaming 'lb25ex' to a more descriptive name (e.g. 'applyLb25Exception') so its purpose in the LB25 rule handling is clearer.
if (this.lb25ex)
src/SixLabors.Fonts/TextLayout.cs:1192
- [nitpick] The variable 'i' could be renamed to a more descriptive identifier such as 'position' to improve code clarity.
int i = current.PositionMeasure;
