 The parent attribute is the originating element of the pseudo-element. For most pseudo-elements parent and element will return the same Element; for sub-pseudo-elements, parent will return a CSSPseudoElement while element returns an Element.

+The selectorText attribute is a string representing the full, normalized selector text used to select the pseudo-element. This includes the pseudo-element name and any arguments, serialized in a form that can round-trip. For example, "::after" for a ::after pseudo-element, or "::scroll-button(left)" for a ::scroll-button() pseudo-element with a left argument.
