chore: perf tweaks for actions/styles/classes (#12654) * chore: perf tweaks for actions/styles/classes - check if we really need to add/remove the class (calling `includes` first is cheaper than always setting/removing it) - check if we really need to update a style (calling `getPropertyValue/setProperty` is expensive) - check if we should call the action's update function (this is not only a perf tweak but also a correctness fix) closes #12652 * changeset --------- Co-authored-by: Rich Harris <rich.harris@vercel.com>
