Re: [whatwg/dom] Match querySelector for pseudo elements (::slotted()) (#463)

You only "accidentally" access nodes that you explicitly ask for.  It doesn't give you access to anything you don't already have access to; `qS(":host")` is the same as just following the `.host` pointer on your shadow tree; `qs("::slotted(...)")` is the same as doing some tree-walking on your own.  Closed shadow trees don't expose themselves via selectors, so won't expose themselves this way either.

I don't know of any other way to "accidentally" access anything outside of your tree; any selectors other than those explicitly mentioned are always limited to just your current tree.

Care would have to be taken with `::part()` so that closed trees don't return anything, but that's it, I think.
