Windows - Smaller Characters

On Windows Chrome - Characters are sometimes smaller than their surrounding characters.

The 5 is slightly shorter than the 1. The font is loaded via TypeKit: https://use.typekit.net/mza8btn.css.

I have reproduced the issue on CodePen with a side by side comparison using the fonts loaded from two different sources: TypeKit and Google Fonts. The issue is not present when loading the fonts through Google Fonts.
