Subject: [PATCH] remove incorrect entries from normalization maps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove scale, contain-intrinsic-size, animation-range, text-box-edge
  from isTwoValueShorthand: these have asymmetric or 3-value semantics
  that make "X X" → "X" collapse incorrect.
- Remove line-height from isLengthProperty: bare 0 is the unitless
  number multiplier, not a length (Chrome serializes as "0" not "0px").
- Fix test: background-size "cover cover" is invalid CSS, use "auto auto".
