RE: [css3-3d-transforms] tranform-origin and % in Z

That's what I initially thought but in that case I'd expect you to treat the value as invalid and ignore it. Instead you turn it into a 2D origin.

When setting the transform-origin to a coordinate using 3 percentage values e.g. '20% 10% 30%',
Safari currently drops the third value from the computed style (see testcase).

Bug ?

No. Percentages are not accepted for the z component of the transform-origin (because it's not meaningful to describe the z offset as a percentage of anything).

This is evident in the grammar <http://www.w3.org/TR/2009/WD-css3-3d-transforms-20090320/#transform-origin-property>.
