v1.5.1

Fixed

• LiveDocumentStyles.GetPseudoStyle no longer throws away every cached generated-box style on each state change. A box is kept while the style it inherits from (the element's, the track's for the slider thumb and fill, the highlight style above for ::selection) and, when a rule for generated boxes reads interaction state, the state are unchanged, and is otherwise rebuilt on its next read from the shared style table. A state change followed by reads of the boxes now allocates nothing in steady state (before, about 800 bytes per pointer move over a range input with input:hover::-webkit-slider-thumb on the page). Computed values are unchanged.
