I've been working through this trying to fix inconsistencies in Gecko but I'm having trouble understanding how this produces consistent results for 2D/3D for input such as `matrix(1, 0, 0, -1, 0, 0)`. As far as I can tell, the 3D decomposition would yield a quaternion of `0, 1, 0, 0` and debugging Gecko and Chrome I see they both give that. However, using the algorithm above we have: > decomp3d.quaternion = [0, 0, sin(decomp2d.angle/2), cos(decomp2d.angle/2)] Which is clearly never going to give `0, 1, 0, 0`. Instead, applying the above logic in Gecko I get `0, 0, 0, 1`. @kevers-google Is there something I'm missing here? -- GitHub Notification of comment by birtles Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/3713#issuecomment-495469151 using your GitHub account
