Summary Optimize style invalidation after class attribute change
Antti Koivisto
Reported 2016-02-10 09:27:55 PST
Currently a class attribute change invalidates style for the entire element subtree for any class found in the active stylesheet set. We should determine exactly which descendants are affected and invalidate just those.
