Incorrect result with non-uniform scale on axis not-aligned to local axis

This is the MaxScript to create a reproducable case:
```
tea = Teapot isSelected:on radius:10
tea.rotation.x = 0.2
scale tea [1,1,5] -- scale in world coordinate (not local coord)
```
Original obj in 3ds Max:

Exported result (I can see the z scale is applied to obj's local z axis):

Run resetXForm does help the exporter exported correctly, but in my case I needed this for instancing, and resetXForm will break instancing.

Start by running the provided MaxScript in 3ds Max and compare the original teapot with the exported result when rotation precedes non-uniform world-coordinate scaling. Done means the exporter preserves the scale relative to the rotated object without requiring resetXForm, while retaining instancing behavior.
