There was a problem hiding this comment.
Copied it from owners-impl.js. But the reason it's not a set is because the test is not seen.contains(target), but seen.some(x => x.contains(target)). The uniqueness of seen itself is guaranteed by the querySelectorAll. Do you think those cases are still improved by using a set?

No, iterating a Set is considerably slower than iterating an array. Given we must do a some, the Array is the right choice.

Yeah. That's what I figured as well.

This looks a bit like "owners" code and some of that code was moved. But a big improvement is that this approach no longer requires us to intercept a child's lifecycle - we never need to call
Owners.setOwner()here. As such, the iterators have become simple static utils which I moved to thesrc/utils/resource-container-helper.js.Also, notice that all lifecycle calls I made via
requiresIdleCallbackwhen available.More specific changes are:
slot.js. These are changes are very modest in size.owners-impl.jshas been moved as a set of static utilities into thesrc/utils/resource-container-helper.js.test-owners.jsand added a bunch of new tests.Partial for #30952.
