We also need this for DocumentOrShadowRoot.adoptedStyleSheets: https://w3c.github.io/csswg-drafts/cssom-1/#extensions-to-the-document-or-shadow-root-interface I'll use a FrozenArray instead for now.

I added some initial support in https://commits.webkit.org/255061@main. It means you *can* have the behavior of an ObservableArray now but it is not yet as convenient as using ObservableArray<FOO> in the IDL.
