PseudoElementChain

A chain of pseudo-elements up to two levels deep. This is used to represent cases where a pseudo-element has its own child pseudo element (for instance .div::after::marker). If both Self::primary and Self::secondary are None, then this chain represents the element itself. Not all combinations of pseudo-elements are possible and we may not be able to calculate a style for all PseudoElementChains.
