LayoutStyle

Remarks

All nine edges are stored, including the Horizontal, Vertical and All shorthands, because CSS resolves them by precedence at read time rather than by expansion at write time: setting All and then Left is not the same document as setting Left and then All, and a store that expanded on write could not tell them apart.

This is around 400 bytes — doc 09's estimate of 120 was made before the edge shorthands and the writing-mode-relative pair were counted. A hundred thousand nodes is therefore about 40 MB in four allocations, against the reference port's several hundred thousand heap objects for the same tree, which is the comparison ADR-006 was actually making.
