Some testcases do not define line-height when setting font-size and this
could lead to problems if reftests are made for these.

font: 1in Ahem;

could be using a 1 to 1.2 line-height value which could create
differences in testcases, namely tiny-but-noticeable-by-softwares gaps.

One example:

Firefox 8.0 will render a tiny white gap between the blue and orange

Firefox 8.0 uses a line-height of 97px (btw, I have no idea where such
value comes from) but it could have been 96px or 96 mult by 1.1
(~=106px) or 1.2 (~=115px) as well, therefore creating bigger vertical
