Anyone else notice a bug using `getRelativeMatrix3D` in Windows? It seems to work fine on Mac browsers.

Specifically, I’m getting a fatal error when I try to get x or y values from something like `this.transform.getRelativeMatrix3D(parent).position.x` (in other words, I’m not using it for a z-depth sorter).
