[cssom-view] Consider adding Element.scrollParent #1522
Description
Suggestion: Element.scrollParent
Returns the closest element which controls the position of current element via a scroll.
This feature is useful in many cases, easy for browsers to implement and hard for plugins such as jQueryUI to get it right.
