The CSSUnparsedValue interface of the CSS_Object_Model#css_typed_object_model represents property values that reference custom properties. It consists of a list of string fragments and variable references.

CSSUnparsedValue.keys(): Returns a new array iterator object that contains the keys for each index in the CSSUnparsedValue object.
CSSUnparsedValue.values(): Returns a new array iterator object that contains the values for each index in the CSSUnparsedValue object.
