A negative outline-offset value should be clamped per spec as to stop it from becoming invisible with large negative values. Spec ref: https://www.w3.org/TR/css-ui-4/#outline-offset Also added a new WPT reftest for this case as no tests existed prior, updated related WPT expectations, and updated a few old layout reftests.
