This patch improves test coverage for the interpolation of transform lists. Specifically, the new tests cover:

  • mismatched list lengths with a partial prefix match
  • mix of exact and primitive (e.g. scaleX & scaleY --> scale) matches

These new tests fail in Chrome without the patch (https://chromium-review.googlesource.com/c/chromium/src/+/1372025) to implement the algorithm outlined in transforms spec (https://drafts.csswg.org/css-transforms-1/#interpolation-of-transforms), but pass when tested in Firefox version 64.0.
