This change came about because I asked about whether or not the misaligned benchmark histograms could be fixed somehow. I think the new font is a smudgeon taller (or at least gives off that effect - we’d have to compare with the old one to know for sure).
Regardless, I think getting font height aligned and consistent across browsers with surrounding font is a much harder task than making it consistently work in a single block of code. Rendering engines are pretty different after all. If you have a specific example in mind, please post a screenshot of what it looks like on your screen!
