SelectorList::next() would be a better choice, I think.
indexOfNextSelectorAfter() calls next(), and is a convenience method for the
RuleData code which stores the selectorIndex.

Yeah, but we still need a selectorIndex here because we call addRule here. Let
me try to use next() here anyway in another CL.

Ah. I didn't notice. Just leave it like this then.
