Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The first element in the array is the origin of this window's parent, and the last element is the origin of the top-level browsing context. If this window is itself a top-level browsing context, then ancestorOrigins is an empty array.
