Since querySelector and querySelectorAll are borked we should implement the scoped version of these.
Once all patches for https://bugs.webkit.org/show_bug.cgi?id=49142 have been landed, this will be exceedingly trivial.
<style scoped> was removed from Spec - https://github.com/whatwg/html/issues/552 and this is extension to those, if I am not wrong but there is further interest here: https://github.com/w3c/csswg-drafts/issues/3547 Do we need to implement these or we can close this bug at the moment and see later on what to do?
Yeah, this is won't fix at this point.
