Should HTMLCollection inherit from NodeList? All the APIs I can think of
that you'd want to add to NodeList you'd want on HTMLCollection as well.

To be clear, array methods that modify the array in-place would silently do
nothing because the properties on NodeLists/HTMLCollections are read-only.
But you'd be able to use things like forEach and filter.
