Re: [csswg-drafts] [css-transforms] Inconsistencies in 2D and 3D matrix decomposition (#3713)

The 2D algorithm flips one scale factor if the determinant is negative whereas the specced 3D algorithm flips all scale factors.  Both have the impact of making the matrix determinant positive --  though in the 3D case, this will lead to rotations in addition to the scaling as well as create a throbbing effect.  If in the 3D algorithm a single axis was selected for scale inversion to address the negative determinant in a consistent manner to the 2D algorithm, the 2D and 3D results should align.
