WindowOrWorkerGlobalScope call information on Window and WorkerGlobalScope is out of date

Should https://developer.mozilla.org/en-US/docs/Web/API/Window and https://developer.mozilla.org/en-US/docs/Web/API/WorkerGlobalScope just reference WindowOrWorkerGlobalScope instead of including everything in the Properties implemented from elsewhere section?
Currently both those pages don't mention crossOriginIsolated and say origin "does not yet appear to be implemented in any browser" even though https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope says it was implemented in Chrome 59 and Firefox 54.

1. Any pages that statically/dynamically fetch the relevant sections from others? We could do similar to fetch properties/methods/events from WindowOrWorkerGlobalScope.
2. Should we just link to relevant sections of WindowOrWorkerGlobalScope and remove the duplicated content from here?
3. Do a one off sync to fix this bug?

We'd like to move these pages and I'm doing that work in #8351. The compat data will also be updated in mdn/browser-compat-data#11518

We removed the abstract mixin page https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope. The exposed interface pages Window and WorkerGlobalScope remain.
