To align with ES6 we should set the [[Prototype]] of the interface object to the parent interface object.

For example:

HTMLElement.__proto__ === Element

I took both testcases landed by Chrome patch and turned it into JSFiddle:

Link - https://jsfiddle.net/nehay27L/show & https://jsfiddle.net/u1v4cbLd/show

Safari 16.1 passes all those tests and I took the latest code of test case from "source.chromium.org".

Do we need anything else? Thanks!
