The other meaning is more like a filter. I was convinced that @scoped worked exactly like this until this thread. Apparently my previous reading of the spec was insufficiently deep to spot the scoping/filtering difference. FWIW, I also think that querySelector got this wrong. It should have scoped by default, and then possibly also offered an option to filter based on an element. ~TJ
