Use the existing animated style update path when document style recalculation reaches an element through inherited style recomputation. Paused or filled animations can contain inherit, rem, rch, or other font-relative keyframe values that depend on parent or root metrics. Those dependencies can change even when the target's inherited computed values do not otherwise change. Make the document traversal opt in explicitly so animation-driven inherited recomputation does not schedule another animation update while propagating animated inherited values. Add coverage for a media-gated root font-size change affecting a paused rem-based animation. Update the font-stretch WPT expectation now that its inherited-animation case passes.
