Details depend on how you are representing ranges in the rendering side and who is caching styles, but basically

1) look up which highlight ranges containing the element being painted
2) with the range/element pairs look up the styles (via getUncachedPseudoStyle)
3) cache the style somewhere (maybe in the range itself, maybe extension of getCachedPseudoStyle).

This is a sort of combination how marker and first-line painting currently works.
