Store the static-position insertion point produced by an inline formatting context and let block layout consume it for originally-inline absolute boxes that follow an anonymous inline wrapper. This removes the block formatting context's fragment-walking reconstruction of the same position. Keep the calculation in IFC aware of forced breaks, aligned inline content, trailing inline margins, wrapped lines, RTL inline content, and vertical writing modes. Keep regression coverage for the static-position cases covered while building this model.
