Hello again,
It would seem that the final piece of my puzzle doesn't want to play nice.

In Firefox there are clearly differences between font width (which should just be font-size), line-height, font-weight, letter-spacing and word-spacing. To combat this, I tired styling each of these properties with exact values (in case browser-default stylesheets were slightly different) as
