When the step unit is set to a positive <length>, the box’s outer height is rounded (see block-step-round) to the closest multiple of the unit. Negative <length> values are invalid. Values other than none cause the box to establish an independent formatting context. In situations where margins collapse, only the box’s own margin is considered in calculating its outer size. When a box fragments, step sizing is applied per fragment. 1933991 1 webkit-bug-importer 2023-02-15 15:37:57 -0800 <rdar://problem/105519481>
