So let's see. If we don't pass a :scope elements argument we get
E.matches(":scope") -> false
E.closest(":scope") -> null
E.closest(":has(> :scope)" -> null
If we pass E as :scope elements we get
E.matches(":scope") -> true
E.closest(":scope") -> E
E.closest(":has(> :scope)" -> E's parent
Now for closest() we could also pass the current ancestor A as :scope
elements, then we get
E.closest(":scope") -> E
E.closest(":has(> :scope)" -> null
It seems to me that passing the element on which the method is invoked
as :scope elements (i.e. E) makes the most sense. That argues for 1).
