3D Transform Plane Clipping Bug

Intersecting Plane Clipping Bug

Intersecting planes should clip. The behavior on the right is correct.

While working on a CSS3 tool we bumped into a nasty little bug with CSS3 3D Transforms. This bug is seen when two planes intersect.

When two planes intersect they should be “clipped”. This means that parts of the faces become invisible – as if the two faces were going through each-other. Unfortunately this is broken in Mozilla Firefox and Google Chrome. Apple gets it right with Safari on their desktop and their iOS devices.
