It's specified by https://webidl.spec.whatwg.org/#idl-observable-array
It's needed by our CSSColor implementation begun in https://bugs.webkit.org/show_bug.cgi?id=238208

We also need this for DocumentOrShadowRoot.adoptedStyleSheets:

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.
