This hook existed because some elements wanted to run script inside ::insertedInto, but that wasn't a safe time. Now nothing can run script inside there so we don't need this extra hook. HTMLStyleElement's usage of this hook is not clear, but it seems like it might have related to a pre-lazy attach bug. R=abarth@chromium.org Review URL: https://codereview.chromium.org/758623002
