Bobby Holley	7fa7936657	Implement attribute restyle hints. ... Fixes #6942.	2015-11-10 11:57:24 -08:00
Bobby Holley	7dba4447f1	Store pristine element state rather than a set of changes. ... This is the strategy we'll need to take for attributes, and so this change puts us in a position to handle attributes and state the same way. This does mean that we stop taking care to track the situations where our state has reverted to the original state, with no net change. I think that's probably of negligible value though.	2015-11-04 19:09:58 -08:00
Bobby Holley	d89816bb5f	Consider all the pseudo-classes in a given compound selector when computing restyle hints, not just the rightmost one. ... For some reason when I wrote this code I mixed up the rules for pseudo-elements (rightmost, maximum of one) with those of pseudo-classes (which have no such restriction). This caused a correctness issue which can be demonstrated with the associated reftest modification.	2015-11-04 19:01:50 -08:00
