It's not very easy to understand on its current state, and it causes subtle bugs like bug 1533654. It could be simpler if we centralized where the interactions between properties are handled. This patch does this. This patch also changes how MathML script sizes are tracked when scriptlevel changes and they have relative fonts in between. With this patch, any explicitly specified font-size is treated the same (being a scriptlevel boundary), regardless of whether it's either an absolute size, a relative size, or a wide keyword. Relative lengths always resolve relative to the constrained size, which allows us to avoid the double font-size computation, and not give up on sanity with keyword font-sizes. I think given no other browser supports scriptlevel it seems like the right trade-off.
